How to force py2app to run app in 32-bit mode

Question

I am trying to build an app bundle with py2app on Mac OS X 10.6. The app uses some libraries which are only compiled for 32-bit, so when the app is run there is an ImportErr

Answer 1

OK, seeing as I work one office over from Vebjorn, possibly this is the best place to post an answer so we will find it again. Given a dictionary of py2app options:

options = {}
...
options['plist'] = { "LSArchitecturePriority": [ "i386" ] }
...
setup(options={'py2app':options})

This creates an array of one string value for the LSArchitecturePriority key.
