I know this could possibly be off-topic, but the errors are OpenMPI errors and
if anyone could shed light on the nature of these errors I 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.
