You'll have to rebuild perl from source if you want threads.  It's a
fairly painless but somewhat lengthy process if this is your first time.
Check out the INSTALL file in /usr/src/gnu/usr.bin/perl - it explains
everything.

Perl threads on Unix aren't nearly as useful as on platforms like Win32
that don't have a native fork(), and even there you have to be careful
because Perl's threads are not at all "lightweight".  You can easily end
up with processes that have huge memory footprints if you don't exert
extreme caution.  Also some modules aren't safe to use in multiple
threads.

Another alternative that's cross-platform and perhaps more robust is POE
(http://poe.perl.org).  This is just a CPAN module, so you don't have to
rebuild perl in order to use it.
