0.6.1b is a bugfix release - see http://sourceforge.net/project/shownotes.php?release_id=257836 I will attach a ebuild to this. It was just renaming, changing SRC_URI and adding a RESTRICT="nomirror".
0.6.1b is already in CVS. Also, RESTRICT="nomirror" is not used for things like scummvm. It is intended for packages that we can't mirror for legal or upstream request reasons.
I only used RESTRICT="nomirror" as a tempomary solution.
