Ack, that's a very good point. I made sure to compile all my other dependencies (NetCDF, IOAPI) with PGI, but I overlooked that one. I'll admit that even after years of working with these models, I'm still never sure when I can and can't mix binaries compiled with different compilers. I used certain flags that should make my PGI binaries compatible with GNU, but I'm never completely sure.
It was the OpenMPI version that came with MacPorts, I avoided the default on on OS X because it does not include a Fortran compiler. I'll try building OpenMPI from source again, I had trouble with orte-clean*, but I can probably get that working or consult the compilation mailing list.
