Newly added Perl QT33 port gives libqt-mt errors

[SKU]

Greetings FreeBSD Questions!

I've tried to get /usr/ports/x11-toolkits/p5-qt to work with no luck.  I have tried to compile with the port and even by hand and keep getting the errror:

freebsd-laptop# pqtsh
/usr/libexec/ld-elf.so.1: /usr/X11R6/lib/libqt-mt.so.3: Undefined symbol "pthread_mutexattr_init"

Thinking that my laptop libraries was hosed, I proceeded to format and reinstall FreeBSD and alas, the same results after reinstalling /usr/ports/x11-toolkits/p5-qt.

So my questions are:

1.  Has anyone else noticed this behavior on stable?
2.  Does this port even work with stable or does it require current?
3.  Can someone help me get this fixed? :)

I am currently running:
FreeBSD freebsd-laptop.geekgod.com 4.9-STABLE FreeBSD 4.9-STABLE #0: Mon Mar 22 10:43:04 EST 2004     root at freebsd-laptop.geekgod.com:/usr/src/sys/compile/GEEKGOD  i386

Thanks for your time!!
