However, it is also possible that conflicting dependencies exist such that they are impossible to satisfy simultaneously. If such a conflict exists in the dependencies of two different packages, then those packages can not be installed simultaneously. You may want to try a larger value of the --backtrack option, such as --backtrack=30, in order to see if that will solve this conflict automatically. For more information, see MASKED PACKAGES section in the emerge man page or refer to the Gentoo Handbook. Running with the "--backtrack=30" option gives the same results, minus the sentence about "You may want to...."
I'm no stranger to tracking down dependencies and ordinary conflicts, but I have no idea about all that python_targets_* crap.
This is a standard useflag conflict. It seems you are trying to purge versions of python other than 2.7 and 3.3. Try 'emerge -upvDN --with-bdeps y @world' first. Concentrate on the packages listed in your output in 'required by'. Anyway, doesn't seem to be a bug.

I am not "trying" to do anything except emerge a package (upgrade, rebuild, doesn't matter). Happens with setuptools, python-argparse, youtube-dl, gentoolkit, etc. In particular, I am not trying to purge any of my installed python versions at this time. I do not have PYTHON_TARGETS set anywhere (/etc/make.conf , /etc/portage/package.* ). Installed python versions are: Available Python interpreters: [1] python2.7 [2] python3.2 * [3] python3.3 python3.3 was installed, but I haven't moved any site packages over to it from 3.2 yet (and I can't, currently). To be clear, I want 2.7, 3.2, and 3.3 left alone, and I am not telling emerge to do otherwise. I don't know how those flags are getting there. Thanks.
@comment 3: in such case, you need either set PYTHON_TARGETS to "python2_7 python3_2 python3_3" globally or at least set those useflags on the packages you want them to be set on.

I set that in /etc/make.conf and the build worked; thank you. I still think it's a bug (albeit a minor one) that, by default, emerge would assume that I want to delete one of my installed slots, especially when it decides "yes" for one package and "no" for another, leading to the conflict.
PYTHON_TARGETS needs to be set to a sane value, therefore profile sets it to *just* the *latest* stable slots for python2 and python3. If you want something else, you need to set it on your own.
