Is it possible that you might have overwritten some of the FC9 files 
with an FC10 MPICH2 install? The error you are getting seems like the 
library files belong to FC9; that's why when you run a program compiled 
in FC9 works, but one that's compiled in FC10 doesn't.

An easy way to try this is to install from source into a different 
directory (not /opt) and try it out from there.

The machine running Fedora 10 is a fresh install, as is MPICH2-1.1. There is nothing from the old Fedora 9 machine. Someone said that Fedora 10 has MPICH2 binaries. Could that be causing a problem if I do a fresh MPICH2 install?
