ps-print-buffer failure latest debian emacs-snapshot?

[Nic James Ferrier]

I'm getting:

Debugger entered--Lisp error: (void-variable ps-mark-code-directory)
  ps-begin-job(ps-generate-postscript)
  ps-generate(#<buffer *mail*> 1 269 ps-generate-postscript)
  ps-spool-without-faces(1 269 nil)
  ps-print-without-faces(1 269 nil)
  ps-print-buffer(nil)
  call-interactively(ps-print-buffer)
  execute-extended-command(nil)
  call-interactively(execute-extended-command)

from ps-print-buffer on the debian snapshot (which tracks head
right?).

Anyone give me a hint what this might be?


I thought I'd be fairly safe upgrading so near release   /8-<
