I'll keep walking through the execution in gdb maybe I'll

The fedora package comes with a debuginfo package that has everything
gdb needs to let me step through the openmpi functions.

So I built openmpi-1.6.5 from the tar ball and of course

and now I can't run even the simplest MPI programs.
I filed a bug report with Fedora's bug tracker :
https://bugzilla.redhat.com/show_bug.cgi?id=986409
My simple program is attached as mpi_simple.c
mpicc works :
