[Pythonmac-SIG] py2app and qt jpeg plugin

[Emanuele Santos]

Thanks Ronald and Boyd,

This is how I finally fixed the problem:
Put an empty qt.conf inside the bundle's resources folder.
Copy the contents of qt's plugins directory to the bundle's MacOS folder
use install_name_tool on the libraries inside the plugins directory.

After that it found the plugins directory, but it couldn't load them  
because the bundle would still also load the system qt libraries (I  
don't know why) and I would have those QObject::moveToThread errors.

To finally solve this, I had to rename the qt directory so it  
couldn't find the system libraries and load only the bundled ones.

I wish I could help with a recipe for PyQt, but I don't know how to  
make one. What I am doing now is just including sip in py2app  
includes option and PyQt4 in the packages option. Of course, I have  
to copy the plugins and relink them after that.

Can we define in the recipe to tell py2app to include the plugins  
directory?

Thanks again,

-- Emanuele.
