After a fresh cvsup of ports tree today portupgrade -R mkisofs-2.0.3_2 fails with Stop in /usr/ports/sysutils/cdrtools. I had moments before successfully portupgraded cdrtools with: portupgrade -R cdrtools-2.0.3_2, so I'm somewhat surprised to see this error here.

This is the tail of the portupgrade failure:
