I may suggest a problem of 'underscoring'. How do you compile your mpi
libraries? What flags were used for ABINIT (typically, I bet on a
-fno-second-underscore)?

To know it, locate your mpi library and do:
nm /path/to/your/library/libmpi.a | less
And look for the symbols with a T, do they have two underscores at the
end?
Then, do:
nm src/18seqpar/libseqparp.a | less
And look for the symbols with a T, do they have only one underscore at
the end?

If so, either recompile ABINIT without the -fno-second-underscore or
recompile mpich with -fno-second-underscore.

Damien.
