problem with route-to on fbsd 5.4

[peceka]

Hi,

i've got problem with route-to rule on fbsd 5.4. all the time when
i've make pfctl -f /etc/pf.conf and wait 30 seconds my machine hungs
up. even keyboard doesn't work.
i've seen on http://pf4freebsd.love2party.net/problems.html that there
was an error with route-to and it was fixed.
So how can i update pf in my fbsd 5.4 box? i don't want to have
-CURRENT on router and i can't install openbsd there.

Best regards,
p.
