[blocks B     ] <gnome-base/control-center-2.17.0 (is blocking

!!! Error: The above package list contains packages which cannot be installed
!!!        at the same time on the same system.

For more information about Blocked Packages, please refer to the following
section of the Gentoo Linux x86 Handbook (architecture is irrelevant):

http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?full=1#blocked

----------------------------------------------------------------

Blocking gnome-control-center in package.mask is not working, since it is a
dependency of gnome-light.

Reproducible: Always

Steps to Reproduce:
1.Run gentoo stable 2007.0
2.emerge --sync && emerge -uNDa world
3.Sit back and enjoy the show

Actual Results:  
Portage can't continue because of 2 to-be-emerged packages which are blocking
each other.

Expected Results:  
Portage should have updated my pc. No I'm not kidding ;)

emerge -C \<gnome-base/control-center-2.17.0

Ok nice ,should have thought of unmerging the control center... I read the page
though, and it states filing a bug :)
