cperl-mode syntax highlighting is broken

Binary package hint: emacs-snapshot

When using cperl-mode that comes with the emacs-snapshot-common package in Ubuntu Karmic syntax highlighting is not working correctly. Sometimes it seems to work for a few lines but as soon as something changes chances are that it stops working. Most of the time syntax hightlighting is broken, only very simple stuff like literals and comments are highlighted.

I could fix it by installing the most recent version from http://github.com/jrockway/cperl-mode (not sure how 'official' that git repo is, but it fixed my problem and I found the link on the Emacs Wiki).
