Tested. This resolves the issues I was experiencing with python-setuptools.

I'm still wondering about the following commit:

$ git show 0c6595a71965e4c1a56902cb7e7ca74f3b469e19

This seems to be addressing similar sorts of issues. In the patch below
you added an RPROVIDES to python-native_2.7.2.bb. I reverted the above
commit and then appended "python-core-native" the the new RPROVIDES for
python-native and the build now succeeds. Is the above commit a bandaid
that is better resolved with the RDEPENDS?
