Comment 5 for bug 449262

Yes, quite.

And that means it also affects not just zc.recipe.egg:custom, but also the other zc.recipe.egg recipes.

And indeed, I just hit that this morning. My buildout builds a specialized python, some custom eggs, and a final egg whose script I want with the other eggs baked in. But the final egg (using zc.recipe.egg) ignores the built custom eggs in develop-eggs since they're all "-i386" eggs and not "-fat" eggs, despite a setting of "python" to the custom python.
