Running jumpnbump-xdialog displays the error: /usr/games/bin/jumpnbump-xdialog: line 12: Xdialog: command not found The X USE flag doesn't seem to change anything.
You can emerge xdialog if you want to use jumpnbump-xdialog. I'm not interested in making it a hard dependency. Basically, yes, the fact that jumpnbump-xdialog doesn't work after emerge is intentional.
Fair enough, but shouldn't the X USE flag be removed?
I think the X use flag is there for X support from libsdl. If you don't have X you can still play with some other libsdl backend.
