The libraries installed as part of this package are scanned as plugins. They do not have specific versioning or the ability to support more than one version on a single platform as omxregister-bellagio only scans the *.so files. The automake config needs to be adjusted to avoid the versioning.
The attached patch is a bit too aggressive. It looks like only the files under libdir/bellagio should be built with the 'avoid-version' option. I'm working on an updated patch.
Updated patch that only disables versioning for libomxaudio_effects, libomxclocksrc, and libomxvideosched.
