Note that py2app needs a considerable amount of attention though:

- copy entire eggs into the .app bundle, instead of just bits and pieces

- an option to specify required eggs in setup.py (like setup_requires,
but for a specific app)
Just yesterday I implemented a bit of post setup() code that allows me
to inject some eggs into my app bundle after it has been created. First
I specify the egg's package name in the packages option so py2app will
include the package and do dependency checks on it, but not put it in
the zip file. Then after setup() has run I remove these package
folders, copy in the egg folders (none of mine are zipped but that
should probably work too) and then create a sitecustomize.py in the app
to add the eggs to the sys.path. This last step is needed because it
looks like the normal .pth file processing is not included in the
site.py used in the app bundle.
Here is a bit of the code from my setup.py, the two names used in the
for loop items are because some eggs use a different egg name than the
package name.
makingAlias = '-A' in sys.argv or '--alias' in sys.argv
if not makingAlias:
base = 'dist/%s.app/Contents/Resources/lib/python%s' % (NAME,
sys.version[:3])
sc = file(os.path.join(base, 'sitecustomize.py'), 'w')
sc.write("import sys, os\nbase = os.path.dirname(__file__)\n")
for distname, pkgname in [('Foo', 'foo'),
('Bar', 'bar'),
('xyz', 'xyz')]:
dist = pkg_resources.get_distribution(distname)
distbase = os.path.basename(dist.location)
remove_tree(os.path.join(base, pkgname))
copy_tree(dist.location, os.path.join(base, distbase),
update=1, verbose=1)
sc.write("sys.path.append(os.path.join(base, '%s'))\n" %
distbase)
This probably isn't enough to use as a base for general purpose egg
support in py2app, but it can at least be used as a stopgap measure
until somebody who knows what they are doing can add support for it in
the right way.
