I'm not sure where the fix needs to go, but if I install mvapich2-1.0.0 
via install.pl, it should also build/install libibumad-devel. 
Otherwise, mpi programs cannot link correctly.  I don't know if this 
dependency should be defined in the mvapich2 srpm somehow or the ofed tools.

But in install.pl I see this:

And see that libibumad-devel is a build requirement.  I claim it is also 
an install requirement.

This all worked on 1.2.5 by the way...
