Despite the ebuild for 2.0.1 being virtually identical to the one for 2.0.0 danish translation is missing for bygfoot-2.0.1. Danish translation works for bygfoot-2.0.0. I don't know whether this is a gentoo-related bug, or if this is a bug from the original package. If this isn't a gentoo-only bug, we should definitely send a bug-report to gyboth (the developer).
Should work now, thanks.
Confirmed. It works :D
