it seems that blackbox ebuild and gentoo package website has a problem with blackbox licences...they doesn't report the same licence as statued on the blackbox website BSD:gentoo website:http://packages.gentoo.org/search/?sstring=blackbox as-is:blackbox-0.65.0-r3.ebuild as is:blackbox-0.65.0-r4.ebuild BSD:blackbox-0.70.0.ebuild MIT:http://blackboxwm.sourceforge.net/AboutBlackbox(blackbox website)
Looks like pyrania has fixed it.
