The error has nothing to do with Fortran; the problem is quite clear - the 
configure script cannot find a C compiler.

Try typing "echo $PATH" at the command line to see which your PATH variable 
includes.  If it does not include the directories within $HOME where you are 
installing software, then add this directory to your PATH:

PATH=$PATH:$HOME/software/bin (for example)

Also, when you are finally able to install Gromacs, at least install the newest 
version (4.0.3) to get the newest bug fixes and revisions.
