Yes. OS X, unfortunately, doesn't really support the C locale APIs.
More precisely, it supports the functions, but they have no meaningful
effect. Python relies on the operating system here, so please bring
this up with your OS vendor.

Likewise. Apparently, the operating system does not support that locale,
so Python cannot support it, either.

On freebsd4, this may help, but you would need to ask in a FreeBSD
newsgroup. On OS X, you just have to wait a couple more OS releases.

Not sure what a namespace is, in this context, but I guess the answer is
