Psi Nightly builds
You can, however, try some of our nightly CVS builds for Debian. These
are compiled to be used on Debian Sarge but are confirmed to work on Ubuntu
Hoary as well.
As these builds are created fully automatic, we cannot guarantee their correctness. This means you can use them at your discretion without any warranty whatsoever.
