[chirp_users] Chirp IndexError

[Benjamin Krueger]

I've installed chirp as per the instructions for OS X. It starts up, however when following the beginner's guide I get the following error when selecting Radio, Download from Radio. This doesn't appear to be a known issue. Are there any suggestions to get this working?

$ sh chirp_osx.sh 
chirpw:55: PangoWarning: error opening config file '../Resources/etc/pango/pangorc': No such file or directory
