I think it's a bug which was already fixed, but currently the fix is only in unstable versions of portage. See [1].

Right, it's fixed portage-2.1.10.49 by this commit:

same problem with portage-2.1.10.49

[Comment 4 Zac Medico 2012-03-06 15:20:03 UTC]

It seems to work as intended for me, which with portage-2.1.10.49.

Please try it without -uD, like this:

   emerge -pv --changed-use gcc

[Comment 5 Zac Medico 2012-03-06 15:27:24 UTC]

Also, see it this triggers it:

   emerge -puvD world

I suspect that --changed-use may not be involved, but rather it's a dependency that's causes it.

ok, now seems to be working (don't know what's different between 3 hours ago, same portage version, same sync ....).

Thanks Zac!
