My head hurts from working on this! I just realized <omp.h> is for
OpenMP, not OpenMPI. So, of course the PGI <omp.h> is used. I still
don't know why otfprofile is failing, but at least that explains why
OpenMPI-1.5rc5 has no <mpi.h>.
Sorry for the noise.

The make of OpenMPI 1.5rc5 fails for PGI 10.3 in otfprofile:
Making all in otfprofile

2 errors detected in the compilation of "otfprofile.cpp".
The errors are coming from an <omp.h> file that comes with the PGI
compiler. I would think OpenMPI would use its own. The problem is,
there isn't one (yet?):
[root@hydra otfprofile]# find /usr/local/src/openmpi-1.5rc5 -name
omp.h
The C++ file that is using the PGI <omp.h> file is ompi/contrib/vt/
vt/extlib/otf/tools/otfprofile/otfprofile.cpp:
[root@hydra otfprofile]# cd ompi/contrib/vt/vt/extlib/otf/tools/
otfprofile
[root@hydra otfprofile]# grep omp.h *.cpp
otfprofile.cpp:# include <omp.h>
I ran the compile from make -n to verify that:
[root@hydra otfprofile]# pgcpp -m64 -DHAVE_CONFIG_H -I. -I../.. -
I../../otflib -I../../otflib -DINSIDE_OPENMPI -D_REENTRANT -mp -g

I don't know how to fix this. Where is otfprofile.cpp expecting to
get <omp.h>? Why isn't it there? I'm beginning to think this
contrib/vt stuff should not be enabled by default. I don't know
that it is needed in general.

We still have one known possible regression:

But we posted rc5 anyway (there's a bunch of stuff that has been
pending for a while that is now in). Please test!
