It hasn't built for all Debian architectures yet, but is available for at

If you aren't sure how to pull in packages from experimental, see:

http://wiki.debian.org/DebianExperimental

I've also put it in a Launchpad PPA for all currently supported Ubuntu
releases, which has built for all of them already:
