I just now ran tests on OpenBSD-5.2/i386 and OpenBSD-5.2/amd64, using Clang-3.1.

Unfortunately, there is a mass of linker error building libmpi_cxx.la (on both systems)

I am trying again with --disable-mpi-cxx and will report my results later.

Using  --disable-mpi-cxx I still have linker problems, now from the C++ lib(s) in VT.

So, I've just gone ahead and tried CC=clang CXX=g++, which worked fine.

Given the VT failure, I am guessing that the issue is clang++, rather than something in OMPI "proper".

OR, perhaps is because my Clang install pre-dates my upgrade from OpenBSD-5.1 to 5.2.

I'll re-install Clang and post new results when I have them.
