[Pyobjc-dev] zlib not available

[Georg S. <geo...@gm...>]

Hi,

I’m just trying to get a plugins I use for my app to use Python3. I installed Python 3.5 (standard installer) and pyobjc (python3.5 -m easy_install -U pyobjc). Then I make a plugin bundle with `python3.5 setup.py py2app`. 
When I then load the plugin I get a 
zipimport.ZipImportError: can't decompress data; zlib not available

Can someone help me with this?

Thanks
Georg
