ghostscript depends on jpeg?

[Greg Troxel]

I have cups enabled, and print/ghostcript ends up depending on jpeg,
such that if jpeg shlib changes and ghostscript isn't rebuild that it
doesn't work.  There is a comment:

  # XXX make sure the local jpeg headers are found before those pulled in
  # indirectly by cups bl3

but the grand plan is not explained.

cups depends on jpeg, but apparently ghostscript has a direct dependency
somehow, but I can't figure it out from the build log.

It seems broken for gs to have internal jpeg anyway.


If no one has better ideas or objections I'll add a dependency on jpeg
in the cups case.

IIRC Postscript would have some non-standard JPEG like images included,
but the details are fuzzy.

  IIRC the jpeg library cannot be built with support for both 8 and 12
bits per components at once, but PostScript supports both, so gs needs
support for both.  (It's been many years, so maybe things have changes
since.)
