Attached is a new ebuild for Jamestown: Legend of the Lost Colony. This was written for the Humble Indie Bundle version (from HIB 4), and specifically tested on amd64. It appears to be available from other sources as well (such as Desura), but I've not tested those.
Game works great. Only odd thing worth mentioning is that it includes a few bundled libraries, and while a two of the three could be replaced by system libraries, the third, libsdtc++.so.6, could not. It looks like (though I've not confirmed) it requires GCC 4.6, which isn't stable in portage, so I thought it better to copy over the bundled library for now. Once GCC 4.6 goes stable, this can probably be removed.
I modeled this on Luca's Braid ebuild from bug 349136, as both use MojoSetup.
Huh. Can't believe I missed that. Sorry about that. Will upload when I get home tonight.
