Those packages follow the exception published in the wiki[1] which
allows license=('MIT') if you also include the exact license text with
copyright notice in /usr/share/licenses/pkgname. This text has been
there since the creation of the wiki page in November 2009[2] and I
believe before that it was on another wiki page that has since been
deleted without preserving its history[3], so I don't know where it came
from. Should this really be declared as wrong now?
