@rough-minister-58256 in case anyone comes around asking these same questions in the future -- the workaround appears to be

docker run -ti --rm=true -v `pwd`/3rdparty/python/wheelhouse/:/opt/wheelhouse <http://quay.io/pypa/manylinux1_x86_64|quay.io/pypa/manylinux1_x86_64> auditwheel repair --no-update-tags /opt/wheelhouse/gevent-1.2.2-cp27-cp27mu-linux_x86_64.whl

-- this will "repair in place" your linux wheel into a manylinux wheel which will carry all of its .so's along with it. In order for this to work, you have to also build your wheels using the same manylinux image, which I did like

docker run -ti --rm=true -v `pwd`/3rdparty/python/wheelhouse/:/opt/wheelhouse <http://quay.io/pypa/manylinux1_x86_64|quay.io/pypa/manylinux1_x86_64> /opt/python/cp27-cp27mu/bin/pip wheel --wheel-dir=/opt/wheelhouse/  gevent==1.2.2
