xetaprime, are you available and willing to help anybody that has followed your guide and ended up with problems with their system? Can you remove and reinstall libc6-dev?
Did you see this in the wiki:
Backporting (recompiling and repackaging) is the only safe way to install packages from Debian Sid or Debian Testing on a Debian stable system. Do not install such packages without backporting. Attempting to "mix" releases, especially by updating your sources.list file, is a sure way to break your system. Recovery in these cases usually involves restore from backup.
I do a lot of packaging for a non-Debian, but Wheezy-compatible community repository, and I sometimes recommend that people try my Wine packages, for example. But I build them against Debian libraries using the Debian tool chain, installed from the Debian repositories, so I know that they are compatible.
If you really want to help with Enlightenment 18, I can help you make packages that are Wheezy-compatible, and you can add them to our repository or just host them someplace. That's the right way to do it.
