I've managed to build fheroes2 for Harmattan!

Though there are several issues left, the biggest one is graphics artifacts on redraw. @mece, did you have this problem on N900?
The package is not available now, but I think it will be soon...

This is brief description of what I have done with a couple of screenshots
