I have Windows 7, Windows xp, Ubuntu, Visual C++, and CodeBlocks:: at my disposal.
The enigma Debian package that I update every now and then is also automatically built for Ubuntu.
I last built revision r2210, which is in oneiric/precise as "1.10~~pre-alpha+r2210-1"
The ~~ version number is to make this version sort "older" than any official alpha or beta release. The current revision is r2236, so not that much newer.
For testing your level editor, this should work well enough.
You can quite easily rebuild the package by following the Ubuntu and Debian instructions for building packages. Updating the package to a newer release is a bit tricky, as I jumped through some hoops to make the package smaller by reusing as much of Debian/Ubuntu as possible. The easiest way probably is to just extract the diff from r2210 to r2236 and apply it to files that exist.
If there is a good reason for me to push a new version to Debian and Ubuntu I can do so. It will probably take some weeks for me to find free time and then for the changes to trickle to Debian testing (+10 days) and Ubuntu (which occasionally pulls from Debian, but the timing is outside of my direct control and knowledge).
