This does not make sense. Either libmpdec-dev is not available in
wheezy, or it is available in wheezy and compatible with wheezy's
libc6. The above message looks as if you're trying to install a jessie
libmpdec-dev binary package in wheezy.

Python 3.3 does not depend on GCC 4.8 for sure, so this could only
happen as a result to some Debian specific patch. I would try to just
build with an older gcc and see what happens (use dpkg-buildpackage -d).

It certainly was relatively straightforward a few weeks ago. I'm running
a wheezy system with Python 3.3 here. But it is possible that the Python
package in testing got some upgrades since then that makes it hard to
backport. Another idea would be to grab the testing python3.3 package
from snapshots.debian.org (try the last version before Python 3.3 became
the default python).
