After installation

Information about how the PATH is setup, is seen here:
http://docs.enthought.com/canopy/quick-start/install_linux.html

After installation, it will add to either HOME/.bash_profile or HOME/.profile or HOME/.bashrc:

# Added by Canopy installer on 2014-06-09
# VIRTUAL_ENV_DISABLE_PROMPT can be set to '' to make bashprompt show that Canopy is active, otherwise 1
VIRTUAL_ENV_DISABLE_PROMPT=1 source $HOME/Enthought/Canopy_64bit/User/bin/activate

It will make a bash activation script in: $HOME/Enthought/Canopy_64bit/User/bin/activate

If a different user, other than the user who installed EPD, would like to use EPD, the HOME/Enthought/... directories is not initiated.
First run the Canopy, to setup the directories.

INSTALLDIR=/sbinlab2/software/python-enthought-dis/canopy-1.4.0-full-rh5-64/
$INSTALLDIR/canopy

That will make an activation source file.

# This file must be used with "source bin/activate" *from bash*
# you cannot run it directly

deactivate () {
    # reset old environment variables
    if [ -n "$_OLD_VIRTUAL_PATH" ] ; then
        PATH="$_OLD_VIRTUAL_PATH"
        export PATH
        unset _OLD_VIRTUAL_PATH
    fi
    if [ -n "$_OLD_VIRTUAL_PYTHONHOME" ] ; then
        PYTHONHOME="$_OLD_VIRTUAL_PYTHONHOME"
        export PYTHONHOME
        unset _OLD_VIRTUAL_PYTHONHOME
    fi

    # This should detect bash and zsh, which have a hash command that must
    # be called to get it to forget past commands.  Without forgetting
    # past commands the $PATH changes we made may not be respected
    if [ -n "$BASH" -o -n "$ZSH_VERSION" ] ; then
        hash -r
    fi

    if [ -n "$_OLD_VIRTUAL_PS1" ] ; then
        PS1="$_OLD_VIRTUAL_PS1"
        export PS1
        unset _OLD_VIRTUAL_PS1
    fi

    unset VIRTUAL_ENV
    if [ ! "$1" = "nondestructive" ] ; then
    # Self destruct!
        unset -f deactivate
    fi
}

# unset irrelavent variables
deactivate nondestructive

VIRTUAL_ENV="$HOME/Enthought/Canopy_64bit/User"
export VIRTUAL_ENV

_OLD_VIRTUAL_PATH="$PATH"
PATH="$VIRTUAL_ENV/bin:$PATH"
export PATH


# unset PYTHONHOME if set
# this will fail if PYTHONHOME is set to the empty string (which is bad anyway)
# could use `if (set -u; : $PYTHONHOME) ;` in bash
if [ -n "$PYTHONHOME" ] ; then
    _OLD_VIRTUAL_PYTHONHOME="$PYTHONHOME"
    unset PYTHONHOME
fi

if [ -z "$VIRTUAL_ENV_DISABLE_PROMPT" ] ; then
    _OLD_VIRTUAL_PS1="$PS1"
    if [ "x(Canopy 64bit) " != x ] ; then
	PS1="(Canopy 64bit) $PS1"
    else
    if [ "`basename \"$VIRTUAL_ENV\"`" = "__" ] ; then
        # special case for Aspen magic directories
        # see http://www.zetadev.com/software/aspen/
        PS1="[`basename \`dirname \"$VIRTUAL_ENV\"\``] $PS1"
    else
        PS1="(`basename \"$VIRTUAL_ENV\"`)$PS1"
    fi
    fi
    export PS1
fi

# This should detect bash and zsh, which have a hash command that must
# be called to get it to forget past commands.  Without forgetting
# past commands the $PATH changes we made may not be respected
if [ -n "$BASH" -o -n "$ZSH_VERSION" ] ; then
    hash -r
fi

Test in bash

Jusy try by:

bash
HOMETMP=/sbinlab2/software

#See current python
which python
which scons
which pip

# Now activate
VIRTUAL_ENV_DISABLE_PROMPT=1
source $HOMETMP/Enthought/Canopy_64bit/User/bin/activate

which python
which ipython
which scons
which pip
which canopy

# Start canopy
canopy

Make a tcsh activation script

If you are using red-hat, the default SHELL is /bin/tcsh.
The environment variables are setup in HOME/.cshrc

You could make a HOME/.cshrc_epd

set VIRTUAL_ENV_DISABLE_PROMPT=1

# unset irrelavent variables
set METHOD=nondestructive

if ( $?_OLD_VIRTUAL_PATH ) then
    set PATH=$_OLD_VIRTUAL_PATH
    setenv PATH $PATH
    unset _OLD_VIRTUAL_PATH
endif

if ( $?_OLD_VIRTUAL_PYTHONHOME ) then
    set PYTHONHOME=$_OLD_VIRTUAL_PYTHONHOME
    setenv PYTHONHOME $PYTHONHOME
    unset _OLD_VIRTUAL_PYTHONHOME
endif

if ( $?_OLD_VIRTUAL_PS1) then
    set PS1=$_OLD_VIRTUAL_PS1
    setenv PS1 $PS1
    unset _OLD_VIRTUAL_PS1
endif

unset VIRTUAL_ENV

set VIRTUAL_ENV=$HOME/Enthought/Canopy_64bit/User
setenv VIRTUAL_ENV $VIRTUAL_ENV

set _OLD_VIRTUAL_PATH=$PATH
set PATH=$VIRTUAL_ENV/bin:$PATH
setenv PATH $PATH

# unset PYTHONHOME if set
# this will fail if PYTHONHOME is set to the empty string (which is bad anyway)
# could use `if (set -u; : $PYTHONHOME) ;` in bash
if ( $?PYTHONHOME ) then
    set _OLD_VIRTUAL_PYTHONHOME=$PYTHONHOME
    unset PYTHONHOME
endif

if ( ! $?VIRTUAL_ENV_DISABLE_PROMPT ) then
    set _OLD_VIRTUAL_PS1=$PS1

    if ( "x(Canopy 64bit) " != x ) then
        set PS1="(Canopy 64bit) $PS1"
    else if ( `basename $VIRTUAL_ENV` = "__" ) then
        # special case for Aspen magic directories
        # see http://www.zetadev.com/software/aspen/
        set DIRN=`dirname $VIRTUAL_ENV`
        set BN=`basename $DIRN`
        set PS1="$BN $PS1"
    else
        set PS1="(`basename $VIRTUAL_ENV`)$PS1"
    endif

    #setenv PS1 $PS1
endif

Then you can at anytime activate the Enthought python by doing

source $HOME/.cshrc_epd
