Were there any warnings when you ran configure? (Such as
"/opt/sfw/mpich-1.2.7p1/bin/mpif90 not found") For some reason, the LOADLIB
variable in your config.h is not being set to include the mpich libraries.
You can look at about line 258 of the configure script to see what it is
trying to do, and maybe figure out what failed (i.e. why the mpichlibs
variable is not being set.) If you understand MPI, you could manually modify
the LOADLIB variable in config.h to include the mpi libraries.
...good luck...dac
