[yocto] Python3-distribute-native build fails in daisy

[Andreas Galauner]

Hi all,

I'm currently trying to add a few python packages to my image for which
I need Python 3.3 because a few of them depend on asyncio. These
packages (asyncio itself, websockets and django) are installed with the
usual distribute setup.py scripts either using setuptools or distribute.

Now when trying to build python3-distribute-native as a build dependency
for any of these packages, bitbake fails with the following message:

(Note: even if the path says openembedded, it's yocto)

When using the devshell to launch python3 and trying to import time, it
fails in the same way.
I'm using an up-to-date checkout of the daisy branch.

Any ideas what the cause for this could be and how to solve this?
