Looks like imake broke the past couple of days:

make: stopped in /usr/pkgsrc/print/ghostscript-esp
** 'cd /usr/pkgsrc/print/ghostscript-esp && /usr/bin/make update CLEANDEPENDS=yes' failed
pkg_comp:current.conf# pkg_chk -C /pkg_comp/packages/pkgchk.conf -asr
/usr/X11R6/bin/imake: Read-only file system
/usr/X11R6/bin/imake: Cannot open Imakefile.c for output.
  Stop.
make: don't know how to make builtin-test. Stop
