Gilles,
You described the problem exactly. I think we were able to nail down a
solution to this one through judicious use of the -rpath $MPI_DIR/lib
linker flag, allowing the runtime linker to properly find OpenMPI symbols
at runtime. We're operational. Thanks for your help.

Sean,
if i understand correctly, your built a libtransport_mpi.so library that
depends on Open MPI, and your main program dlopen libtransport_mpi.so.
in this case, and at least for the time being, you need to use
RTLD_GLOBAL in your dlopen flags.
Cheers,
Gilles

Folks,
For our code, we have a communication layer that abstracts the code that
does the actual transfer of data. We call these "transports", and we link
them as shared libraries. We have created an MPI transport that
compiles/links against OpenMPI 2.0.1 using the compiler wrappers. When I
compile
