Yes, this had long discussion and was done very reluctantly.

was the commit but there was a lot of discussion on the list before it
merged.

Merging a QA test which causes hundreds of warnings isn't really going
to help unless we have a strategy for fixing it.

As I understand it, if you install python 32bit and 64 bit, you should
get the libraries from both but only the binaries from the one that
wins. That should mean anything linking to the lib should work?

What am I missing? Is something not working like that? Is this with the
rpm or opkg implementation? (they're very different)

Cheers,
