Hi again :-)

Happy holidays :-)

It seems there is serious break in compatibility, but can be fixed by ugly
way. Maybe just to add patch below, and to search libipt AND libxt (for my
case i just edit and change libipt to libxt, but it can be handled in more
smart way.
After i apply all this - it seems working fine.

There is trivial patch also, for bug (IMHO bug) in searching lowercased
library. If patch not applied - second time it will try to open lib_dir by
dlopen:-)

Sorry for probably bad style/code, i am not programmer at all.
