for the most part, the libraries are in their own subdir,  the issue is they link against the sun libraries that only
exist on one side or the other...
Technically the only thing that is really different is the soft link name though I haven't got through them all yet.

I will look at the a fore mentioned packages and see if I can get everything to work harmoniously.
