At the moment, the python_target_python3_4 use flag is "stable-masked"
while the necessary packages are being stabilized. I know this is a
bit confusing, but it should not break anything. You can continue
using python3.3 for a while if you like.

For reference, see the following.

profiles/base/use.stable.mask
https://bugs.gentoo.org/show_bug.cgi?id=522322
https://bugs.gentoo.org/show_bug.cgi?id=524416

Once the stablereq bugs are resolved, I will remove the entry from
use.stable.mask.

In the meantime, you can unmask the pytho3_4 flag locally by creating
the following entries in /etc/portage.

mkdir -p /etc/portage/profile
echo 5 > /etc/portage/profile/eapi
echo -python_targets_python3_4 >> /etc/portage/profile/use.stable.mask
