William,
the link error clearly shows libcaffe.so does require C++ bindings.
did you build caffe from a fresh tree ?
what if you
ldd libcaffe.so
nm libcaffe.so | grep -i ompi
if libcaffe.so does require mpi c++ bindings, it should depend on it
(otherwise the way it was built is questionnable)
you might want to link with mpic++ instead of g++
note mpi C++ bindings are no more built by default since v2.0, so you
likely have to
configure --enable-mpi-cxx
last but not least, make sure caffe and openmpi were built with the same
c++ compiler
Cheers,
Gilles

I know this could possibly be off-topic, but the errors are OpenMPI

figure it would be this group:

I've read this may be due to a dependency of Caffe that uses OpenMPI
(since I've been told Caffe itself doesn't use OpenMPI).
Would adding -l directives to LIBRARIES line in the Makefile for
Caffe that reference all OpenMPI libraries fix this problem?
For example, -l mpi.
Thank you in advance. Hopefully this isn't entirely OT.
William L.
