Freecnc which compiles nicely on maemo sadly is in unplayable state, openredalert I'm afraid same situation (last update 3 yrs ago), openRA depends heavily on mono and got me this with 2.10 libs installed:
OpenRA.FileFormats/FieldLoader.cs(121,79): error CS0589: Internal compiler error during parsing
OpenRA.FileFormats/Support/Stopwatch.cs(23,68): error CS0589: Internal compiler error during parsing
OpenRA.FileFormats/Support/Timer.cs(22,39): error CS0589: Internal compiler error during parsing
OpenRA.FileFormats/ColorRamp.cs(39,41): error CS0589: Internal compiler error during parsing
Compilation failed: 4 error(s), 0 warnings
