Having said that, increasingly a lot of programs seem to rely on glibc >=2.14, and wheezy (current stable) only has 2.13.
Apt-pinning:
Edit the following files:
/etc/apt/sources.list
deb http://ftp.iinet.net.au/debian/debian wheezy main contrib non-free deb http://ftp.iinet.net.au/debian/debian wheezy-backports main deb http://ftp.iinet.net.au/debian/debian jessie main contrib non-free
/etc/apt/preferences
Package: * Pin: release a=testing Pin-Priority: 10 Package: * Pin: release a=stable Pin-Priority: 900
Then run
sudo apt-get update
Installation
Installing glibc >=2.13 from testing
sudo apt-get install -t testing libc6-dev
Every package you install takes you closer to trouble...
