At first, on all Systems this file exists, but in /usr/lib64, not /usr/lib:

Seems to be the right place in an x86_64 system.

In ceph.conf there is no setting regarding to lib path.

Is ceph-radosgw needed for rbd? I think not, while radosgw is AFAIK the
REST interface...
This package is not installed (due to a not resolveable cgi dependency).

Mario
