best way to install package from wheezy on squeeze

view story

http://serverfault.com – I want to use doxygen on my Debian Squeeze server, but I need the version from Debian Wheezy because this apparently contains the bugfix I need. It's not in backports -- check packages.debian.org/search?suite=squeeze-backports&searchon=names&keywords=doxygen (I'm new here and wasn't allowed this as a proper link!) I tried adding Wheezy to my sources.list file and running apt-get install -t wheezy doxygen but it wants to install too much from wheezy; This is a production server so can't afford this risk. I'm assuming that compiling from source is going to want to compile all the res (HowTos)
