I wish I waited a little bit longer before asking since I found the
OCPI_LOG_LEVEL environment variable.

I have a Centos7 lxc running as a supported installation, versus my Ubuntu
one to try to do A/B comparisons on. Here is what I found, but I have
absolutely no idea what would cause these things to happen.

It seems like my candidate .so files are being seen, but rejected by Ubuntu
and not on Centos7.

I'll try taking a look at OcpiLibraryAssembly.cxx, but I wouldn't imagine I
should have to do that to simply add the new platform. Any insights would
be useful.
