Ok, this may take a while. The basic problem is that a number of
patch files in pkgsrc didn't follow the pkgsrc rules on making patch
files and ended up with $NetBSD$ expansions that don't match what
was committed to cvs. There is no easy solution from the git repo
side because any corrections we make will cause merge problems later
on.
For the moment a workaround is to 'bmake makepatchsum' in the effected
directories.
