Trying to run python-updater (need to unmask a package)
 

Ok, well first of all I was trying to set up gnome on my new gentoo install (this is the first time I've done this) and it was going fine, but halfway through emerge gnome it would stop with the error "no module named libxml2" After poking around I found out that to fix this I needed to update my python with python-updater. However when I try to do this it says

!!! All ebuilds that could satisfy "=sys-libs/cracklib-2.8.10" have been masked. etc

And so, after poking around more I found out that to unmask it I would have to either add "=sys-libs/cracklib-2.8.10" to /etc/portage/package.unmask or add "=sys-libs/cracklib-2.8.10 ~x86" to /etc/portage/package.keywords. I wasn't sure which, so I tried both and neither worked (my arch is x86 by the way.) So any ideas as to how I should unmask it now?

edit: fixed, turned out I didn't have 2.8.10, I had a later version, but python-updater was looking specifically for that version. After updating world, it conversely updated python, and then after that python-updater worked.

Try adding this to package.keywords:

sys-libs/cracklib ~x86

Also, check to see if the package has been "hard-masked" instead of just masked.
