Unless you're using Gentoo or some other system with automatic
dependency resolution, you'll need to manually check that you have

the readme for details.
For Debian, Rolf Leggewie is the maintainer for gjots2
and you should be able to do a apt-get install gjots2.
There is a Debian package documentation page for gjots2 at:
gjots is now distributed by the Fedora project (as of f-14) - so
you can now just do a 'yum install gjots2'
Other systems - use "python ./setup.py install [ --prefix=/usr... ]" from the tarball
