Well, even if you probably don't appreciate it right now it's a very 
good thing (TM). Gromacs tries to use your default MPI compilers 
(typically mpicc, but you can set it in the variable MPICC), but for 
some reason it isn't even possible to compile a small program to 
check the size of an integer.

Check config.log and try to find out what's wrong with your MPI-
enabled compiler.

Cheers,

Erik
