I should have been clearer on that.  It shows up in the server window
of xchat2 and not an xterm.

Did the perl.so really autoload for you or did you have to load it
manually?

BINGO!!

Yes, you are correct ;-)  I deinstalled Perl 5.6.x and installed
perl-5.8.2_5 and no crashes when manually loading the perl.so and the
scripts.  I suppose I'll need to recompile a few other non-related
perl modules now.

The message in the xchat server window is still there, but the
perl.so loads fine manually along with the perl scripts.  I've
not given it all a thourough testing yet but it seems to be a
solution.

I had also reconstructed an older xchat ports skeleton from CVS 
(~ 2.0.7_1) which was just prior to the update to 2.0.8 and things
work fine.  The perl.so loads (manually in that version) and the
Obsidian fserve seemed to run.

I went back to the xchat website and couldn't find any mention of
needing a particular version of Perl for the new interface and our
port will need to check for that in the Makefile.

I still think there might be a minor issue with "autoload" since I'm
still seeing that message.

Thanks for thinking about the Perl version!  I'll still be available
to do any other testing needed, just let me know.

Best regards,
