Why does GitZilla's update hook throws an error message on push?

Configured everything as stated on the Gitzilla website.

My git repo is working fine for weeks now... Bugzilla is working fine also...

After ending the config of Gitzilla, i branched and tested to see if i could push and it gets logged... it gives me this error:

You need to install pybugz - I had exactly the same issue

git repo is here https://github.com/williamh/pybugz

See requirements Requirements ............

To install and run GitZilla, you need:

• Python (tested with 2.6.4, should work with >=2.5)
• pybugz (tested with 0.8.0)
