Problem with portupgrade on 4.11-STABLE

[atk2 at arctic.org]

For the past month or so I have a couple of ports that will no longer
build on upgrade (graphics/libaux and x11-fonts/XFree86-4-fontEncodings)

The precise error is:

==>  Configuring for libaux-1.0_1
imake -DUseInstalled -I/usr/X11R6/lib/X11/config
In file included from Imakefile.c:16:
/usr/X11R6/lib/X11/config/Imake.tmpl:2136: noop.rules: No such file or directoryIn file included from Imakefile.c:16:
/usr/X11R6/lib/X11/config/Imake.tmpl:2149: noop.rules: No such file or directoryimake: Exit code 1.

I presume that I have something out of date that CVSUP/portupgrade failed
to pick up on but I'm not sure what...

Any suggestions ?

Thanks
