vhdl/Makefile REQUIRES line includes ps-print-nomule, which is now
deprecated.
Trying to build with the current sources yields the expected error:
  expand-file-name(nil "../..")
  (expand-file-name package (expand-file-name (cdr ...) "../.."))
  (let ((dir ...)) (cond (... ...) (... ...) (... ...) (... ...) (t dir)))
  # bind (package)
  package-name-to-directory("ps-print-nomule")
So, I try to remove ps-print-nomule from the REQUIRES line, and I get
the not unexpected:
  # (catch top-level ...)
>Error occurred processing vhdl-mode.el: Cannot open load file:
ps-print 
OK, so then I add ps-print to the REQUIRES definition and I get:
>Error occurred processing vhdl-mode.el: 
ps-postscript-code-directory isn't set properly
I don't actually use or install the ps-print package; do I really have
to configure it in order to build all the packages?
Thanks,
