Hi,
I am trying to install GROMACS-4.0.5, but while making mpirun with the
option --enable-mpi it gives the following sets of errors:

The important thing to note is that I have successfully compiled and
installed mpi version of mdrun on the same machine, for GROMACS-4.0.4.
What am I missing here?
Probably you've changed/removed your MPI library between configure and
make, or between versions of GROMACS, or something similar. Unpack a
clean GROMACS tarball and start again with configure.
