Matthew,
What configure options did you use?
I can try to replicate your findings, as best I can, using the Intel
compiler on my desktop Mac (Leopard). One thing I want to investigate
is which libutil is supposed to be linked. There is no -L in the
failing link step. Is that possibly the error?
I have PGI and about five other compilers on our cluster. I'll get to
OpenMPI 1.4.3 with all those as soon as I fetch the latest versions
and reinstall my cluster software (Rocks just came out with 5.4.3).

Hmm, I tried the recommendation above, adding -Wl,-
search_paths_first, and I still ran into the same issue. I suspect
it is an issue with PGI.
Meanwhile, I've been able to get my applications (CMAQ) working with
MPICH2, so for now at least I am going to continue with that.
Thanks for the responses!

FWIW: I build OMPI on Mac OS-X (Snow Leopard) every day, without
adding any extra flags, without problem. The citation below relates
to something from a long time ago, I believe - haven't seen that
problem in quite some time.
I do not, however, use PGI. We regularly have problems with PGI on a
variety of systems, and I suspect you are hitting one here - but
can't confirm it as we don't have PGI licenses to use for testing.
The Xgrid support is broken, but has nothing to do with the problem
you describe. Just means you can't launch via Xgrid.

Matthew,
I have the same type of error on a completely different software
package on Mac OS X. The error occurs because of the way that Mac
OS X searches for -lutil. If the libutil.a ORTE needs is theirs,
i.e., not the system libutil.dylib, then you have exactly the same
problem I did.
Here are my notes for the fix using gcc. You will have to find out
the equivalent method to pass the -search_paths_first linker option
using pgcc.
# Mac OS X searches for shared libraries before static libraries.
Thus, -L<ours> -lutil finds the system libutil.dylib
# before our libutil.a, which causes undefined references in the
link step because it is using the wrong library. The
# ld -search_paths_first option forces ld to search each directory
first for a matching library, instead of all directories
# first for a shared library.
# Note: this is the form to pass -search_paths_first to ld when $
(CC) is the linker command in makefile.ux
export LDFLAGS=-Wl,-search_paths_first

I hope this problem merits being posted here.
On OS X (Snow Leopard, and Lion), I cannot seem to build Open MPI.
After a lot of building, I get the error:
/bin/sh ../../../libtool --tag=CC --mode=link /opt/pgi/
osx86-64/10.9/bin/pgcc -DNDEBUG -O2 -Msignextend -V -export-

_orte_errmgr_base_error_abort in libopen-
rte.a(errmgr_base_fns.o)
ld: symbol(s) not found for architecture x86_64
This is with the PGI 10.9 compiler, OpenMPI 1.4.3, platform is 86x64
The README does not list PGI as a compiler that OpenMPI was tested
with, and there are notes about it's support for XGrid being
broken (I'm not sure if this is related.)
I seem to get the error regardless of which configure flags I'm
using, just for completeness though, here are the flags I am using:
./configure --prefix=/usr/local/openmpi_pg --enable-mpi-f77 --
enable-mpi-f90 --with-memory-manager=none
Has anyone else got or fixed this error?
I looked at other postings in this list, such as http://www.open-mpi.org/community/lists/devel/2007/05/1590.php
, but they didn't help much.
