Not all SP2's have the MPI-F library (it costs money).  All SP2's have
mpxlf (as far as I know) -- they just link in MPL at least.  You'd still
use mpxlf to *link* MPICH programs on the SP2, although it's not necessary
to compile with mpxlf.

It doesn't seem that the reported error would be fixed using mpxlf, or my
guess is that mpxlf is already being used to link...
