Equivalent to the above (I believe):
cd $AMBERHOME/AmberTools/src
./configure_mpich gnu
This puts all the required libraries and executables into your Amber tree,
(so that it won't interfere with other MPI installations on your system),
ensures that flags like --enable-f77 and --enable-cxx are set (so it works
for things other than pmemd.cuda), adds flags for MacOSX, etc.
If you find problems, let us know, so that we can update the configure_mpich
script so that everyone benefits. Using a "standardized" mpich installation
script also makes it easier for developers to help on the mailing list, since
it helps avoid some trivial problems with hand-installation, such as not
having write privleges in /usr/local, etc.
