If you're still using 2.4.1 you're going to want to add
LSPrefersPPC=True to the plist. Otherwise your app will not run on
i386, because it will not know to use Rosetta.

That could be handled with recipes, or with eggs when py2app grows
support for that. Recipes or workarounds are the only way until then.

That's a bug, but not the right fix. Trunk is fixed.

That should be part of a matplotlib recipe.

Sure, someone can write the recipes and send me a patch. I don't
currently use matplotlib, numpy, or scipy nor do I have an example I
can test with so I'm not going to do it.
