We are aware of the problem and many of these leaks are already fixed in
the trunk and 1.8.2 nightlies.

Hi,
I have been doing a lot of testing/fixing lately on our code, using
valgrind to find problems. Unfortunately, OpenMPI causes a lot of
'false positives' in our testing due to memory leaks of its own.
It appears that MPI_Init allocates a lot of memory blocks that
MPI_Finalize never bother
Can you pass along the cmd line that generated that output, and how OMPI was
configured?

These messages are normal for RPM.
Keep in mind that you're installing the source RPM -- not a binary RPM. Most
people use the source RPM in an rpmbuild command (to build a binary RPM for
their environment), not installing directly.
