[ewg] [mpich2-dev] Problems with mvapich2-1.5.1 - shared library is missing hwloc_* functions.

BTW - in case it wasn't clear, this is the mvapich2-1.5.1 rpm that comes with OFED 1.5.2-rc6.

Hello all,

I'm trying to build mvapich2-1.5.1 on an RHEL 5 update 3 system. It builds from the SRPM just fine, but when I try to compile test programs, they don't link. It appears that a set of routines, hwloc_* are missing from the shared library.
