Question: do you have a gentoo-sources less than 2.6.20-r6 installed?
If not, then the output is appropriate (can't unmerge what you haven't
merged).

The "NS" indicates that this version (2.6.20-r5) is not installed, which
would make sense if the answer to the above question is yes.
e.g:
$ epm -q automake
automake-1.9.6-r2
automake-1.10
automake-1.7.9-r1
automake-1.8.5-r3
automake-1.5
automake-1.6.3
$ emerge -Cp '<automake-1.7'
>>> These are the packages that would be unmerged:
sys-devel/automake
selected: 1.5 1.6.3
protected: none
omitted: 1.9.6-r2 1.10 1.7.9-r1 1.8.5-r3
$ emerge -Cp '<automake-1.5'
>>> These are the packages that would be unmerged:
--- Couldn't find '<automake-1.5' to unmerge.
