Hello,

Assuming the mess with egg-info files is unfixable, here's a patch for
it plus some cleanup to what floppym added earlier.

The idea is that we copy the bundled egg-info files in python_compile()
to create initial versions of eggs in ${BUILD_DIR}. Then, all
the defaults from them are respected while we override the dir.

Patches sent as replies.
