We have two installs of openmpi-1.2.3
One with the pgi compilers the other with gcc/Nagf90
One the pgi compilers does not link against libibverbs, but ompi_info

The other built with Nagware links against libibverbs. It also shoes
in ompi_info the openib btl.
What would cause this? It just pointed out that our login nodes
(most of our cluster does not have IB) don't have libibverbs making
code not link. Any insight from an OFED master would be great.
Did you build the gcc/Nagf90 version with --enable-static or --
disable-
dlopen?
See the thread starting here:

Yes,
Looks like Nag requires a library that was not compiled with -fPIC,
and the linker complains.
Looks more like a bug in our load, our login nodes were missing
libibverbs.a while the computes nodes do have it.
