So the problem is that usr/lib/debug/usr/bin/simpleopal is found in two
packages: libopal3.6.6-dbg and libopal3.6.4-dbg.  The solution is:
- either simply remove simpleopal debug file
- or create another package, simpleopal-dbg, and put the debug file inside
- or make libopal3.6.6-dbg conflicts with libopal3.6.4-dbg

The best quality solution is the 2nd, but is it worth to create another
(debug) package for that?
