Problem upgrading system

[tgc47]

I tried to upgrade my system by doing the following:
1. emerge --sync
2. emerge --update --ask world

but got an error message on step 2
!!! Error: The above package list contains packages which cannot be installed
!!! on the same system.

Here is the full output:
emerge --update --ask world

These are the packages that I would merge, in order:

Calculating world dependencies ...done!

Any idea what's wrong here?
