Wait, the libraries in question are provided along with the lightworks
package?  If so, these private libraries should probably *not* go into
the system path, and in fact this probably won't even work because the
program most likely hardcodes the location of the libraries instead of
checking the system path.

If I understand you correctly, your only problem is RPM's dependency
generator writes out some bogus requires from these private libraries.
 That's easy to fix:
