Description:
When I try to open window preferences of guake it crash.
If I launch guake and try to open window preferences with 'guake -p' I get:

Traceback (most recent call last):

Additional info:
* guake 0.3.0


Steps to reproduce:
After launch guake, try to open prefences windows with
$ guake -p

Note: An ugly fix is creating the directory site under perlbin path, with mkdir -p /usr/bin/perlbin/vendor this problem seems to be more far than guake, maybe many app's depend on it, so i will research, for now you can fix the error creating the directory.

Note2: I found a hack, the error is that a function is based on other linux tree dir structure and he doesn't found the dir /usr/bin/perlbin/vendor so you have to add on the code an exception to skip that dir, and everything works good.

I've mailed to the developers, and i hope a soon answer, with the patch that i've added you have to do

# patch /usr/lib/guake/guake.py -i preferences-window.patch

and that will add the line that skip vendor dir, but i hope to get an answer from guake dev's to see what expected to do with that line, to see how fix it in a natural, transparent and optimized way.

Note3: I contacted the guake developers (lincoln) and he told me that this week will go out a new release with that bug fixed, until now we can add an official patch, the package was updated so this thread is close update to guake 0.3.0-2.

The problem it was already on many distros, not just arch, so i look for some help in the community.
