Arch Linux

Ever since the upgrade to the latest perl my Irssi setup has been behaving quite weirdly. I get error messages for virtually every perl script it tries to load:

09:46:02 Irssi: Error in script repeat:

[stijn@hermes ~]$ grep perl /var/log/pacman.log |tail -1
[2009-09-26 17:25] upgraded perl (5.10.0-6 -> 5.10.1-2)

A rebuild seems to fix it.
