[gentoo-user] World update and dev-lang/python-exec weirdness...

[Tanstaafl]

Ok, I don't understand this...

If I do an emerge -pvuDN world, it tells me I only need to update (among 
a few other things) ONE version of dev-lang/python-exec: (2.0.1 to -r1).

I then tried to selectively update just the kernel, and it complains 
about python-exec-2.0.1 being masked, so I add that to the emerge command:

emerge -pvuDN dev-lang/python-exec gentoo-sources

This results in no blockers, BUT, NOW it wants to update TWO versions of 
python-exec: dev-lang/python-exec 2.0.1 AND dev-lang/python-exec-0.3.1 
(to -r1).

First question is, why does a plain emerge -pvuDN world NOT want to 
update both of these?

Second questions is, do I even NEED both of these? Or can (or more 
importantly, SHOULD) I just emerge -C dev-lang/python-exec-0.3.1?

Thanks,

Charles
