MPICH2 binaries are available in Fedora 10 as much as they are
available in Fedora 9. It is not installed by default though, you must
have asked for it, if the rpms are installed on your system.
I also think your problem is caused by trying to link binaries from
incompatible archs. Can you provide more details on these systems,
like the output of 'uname -m', 'rpm -qa mpich*'
