Sorry I don't usually use gmail web interface...

So by Internal Python modules what do you mean? If that's just the
stuff used in cranking bitbake and OE then why does it need to
generate the manifest in the recipes?

Building some python modules from scratch looks ugly. Is there
anything stopping me from just using easy-install? ... Or would that
be even harder? Seems odd that native recipes don't use easy-install
unless there is a good reason not to.
