Debian Packaging Guide for GNUmed
The latest packages in Debian can always be found through
Debian's package search
Andreas Tille recently posted a guide on how to roll private deb packages in case you cannot wait.
It is actually not that hard. Basically four steps:
1. Rename the tarball to gnumed-client_<version>.orig.tar.gz
(mind the underscore before the version!) and unpack the
tarball
2. Copy the debian directory into the unpacked source directory.
(you can obtain the current debian directory either by
'apt-get source gnumed-client' or from SVN)
3. Edit debian/changelog to reflect the new version and
say 'debuild'
4. Install the resulting packages.
This might even be an option to backport a new gnumed version
to a stable system if you fear the dependencies from testing.
