 To facilitate ghostscript use of shared macports libjpeg instead
 of compiling in the bundled sources, it is desirable to

 1) install one more header, describing "semi-public" interface to the
 library
 2) add a patch allowing processing of slightly non-standard files.

 Details are at

 http://www.ghostscript.com/pipermail/gs-code-review/2002-March/002275.html

 Now macports port of ghostscript does not attempt to use macports
 libraries, hopefully for good reason, but if and when it will try to
 provide shared library interface to ghostscript (libgs) that decision may
 be reevaluated. Why not get ready for that?
