Reported by Richard Hedges:

srun: symbol lookup error: /g/g0/rhedges/DARSHAN_3/darshan-3.0.0-pre2/Install/lib/libdarshan.so: undefined symbol: __real_PMPI_Gather

Starting to look at this at LLNL, hit a problem w the BGQ version…

It looks like problem in defining PMPI_Gather is related to NOT having a DARSHAN_FORWARD_DECL and MAP_OR_FAIL for PMPI_Gather in darshan_bgq.c or conditionally in darshan-core-init-finalize.c
