Many thanks guys, this thread was most helpful in finding the fix. Paul H. nailed 80% of it on the head in the post where he identified the Makefile.am change. That Makefile.am change was due to three things:
1. Fixing a real bug (elsewhere in that commit) 2. My misunderstanding of how module files work in Fortran 3. The fact that gfortran, Absoft, and ifort *don't* require you to link in the .o files generated by modules, but apparently pgfortran *does* Blarg. That led to the duplicate symbol issue which Paul also encountered when he tried to fix the original problem, so I fixed that, too (which was a direct consequence of the first fix). Should be fixed in the trunk now; we tested with pgfortran on Craig Rasmussen's cluster (many thanks, Craig!). CMR is https://svn.open-mpi.org/trac/ompi/ticket/4519.
