versions (minus any PKGREVISIONs) less than or equal to the latest
version of each ghostscript available in pkgsrc (minus any PKGREVISIONs).
For example, if the print/ghostscript-esp is at 7.10, then the list of
patterns for ghostscript-esp should match all versions <=7.10, which is
[0-6].* 7.[0-9]* 7.10
dependency on ghostscript. This handles the dependency patterns that will
match either ghostscript{,-nox11} and ghostscript-gnu{,-nox11} depending
on which version number of ghostscript is required. From the comments at
the top of the file:
To use this Makefile fragment, simply:
(1) Optionally set GHOSTSCRIPT_REQD to the minimum version number of
Ghostscript required by the package,
(2) Optionally set USE_GHOSTSCRIPT to "build" to only add a build-time
dependency on Ghostscript,
(3) And include this Makefile fragment in the package Makefile,
