Comment(by stefan+macports@…):

 I wasn't able to successfully use your latest portfile out of the box. Zim
 does not start with python 2.7, so I have to install the python2.6
 variant.
 This however makes zim's setup.py fail at checking if the HOME env
 variable holds a directory. Removing the check in zim/config.py works
 though.

 Apart from these things, I've added the app portgroup to create an app
 bundle and changed a few things to make the bundle actually start zim from
 i.e. spotlight.
