Hi Richard,

What I meant by OpenMPI group is that HWLOC is developed and released
by them, separately from their MPI stuff.

Apparently though you do seem to have HWLOC installed, but under a different
directory. We can handle this, but I think if the PKG I sent is working
for you, the
issue should be moot.

How is the new PKG I sent working for you?
