This package requires wxGTK-2.6, which is being removed soon.
this program is way too awesome to just let it die from bit-rot. I've been sitting on this patched version for a while. Patch applies to latest version 0.7.2. After applied it will compile against wxGTK-2.8. Also updates the sigc++ dependency. Fixes some other random stuff too. Credit for the patch goes to Torben Hohn.
