Since this did not receive great interest I tried to hack
this myself. I think I'm pretty far now. Most of the
tests pass:

====================================
10 of 101 tests failed
(5 tests were not run)
Please report to address@hidden
====================================

What I didn't figure out is how to pass -mshared flag
to compiler when checking if dlopen is in libdl. Could
somebody give me instructions how to do that?

I have attached a patch against current CVS HEAD. Could
somebody review changes I have made?

Thanks,
Olli
