I don't have any direct experiences with FC6 packages.  This feels like it 
maybe a problem with how the RPMs were built. 

Try locating where the plugins were installed and set the environment variable 
LIBEXTRACTOR_PREFIX to the directory above (so that the plugins are in 
lib/libextractor/*.so).  That *may* help.  Alternatively, you might just want 
to compile LE by hand -- should not be hard.
