The current ebuild is for version 0.10.16 and has been bumped upstream a lot lately (lots of bugs fixed). I renamed the ebuild to the latest version 0.10.20 and tested it. So far it works fine, better than 0.10.16 at least. Version 0.10.16 seems to loop infinitely which led me to see if this was solved in a newer version. It _seems_ this got resolved now. No dependencies changed from 0.10.16 as far as I can see.
