Debian source and i386 binary packages are available at the Alioth pkg-gambc project. This renews the gambc package in Debian which was orphaned some time ago. We are working towards an upload into Unstable.

Please try these packages. If you identify bugs, please post them to the pkg-gambc Tracker, and not to Debian Bug 283299.
