[PlanetCCRMA] LADSPA categorization not working

[Paul Coccoli]

How do I get apps to use the RDF files for LADSPA categorization?  I
have the rdf files, but the only category that shows up is "Spectral,"
with 3 plugins in there.

[paul at localhost ~]$ ls /usr/share/ladspa/rdf/
blop.rdf  caps.rdf  cmt.rdf  swh-aux.rdf  swh-plugins.rdf  swh-scales.rdf

I checked ardour2, rosegarden, jack-rack...no go.  Is there another
package that needs to be installed?

This is on F7.
