Install numpy via pip (don't install scipy, as it causes problems with scons!)
pip install numpy
Download the relax source release [http://download.gna.org/relax from here]. (e.g. http://download.gna.org/relax/relax-2.2.5.src.tar.bz2)
Then unpack it into a seperate directory inside '''/usr/local/'''. '''cd''' into the directory, type
scons
to make the relaxation fitting modules. Then link the relax main program into '''/usr/local/bin''' with '''ln -s'''.
