* print/ghostscript{7,8,9,9-agpl}-base
Installs Ghostscript binary, libgs, and related files.
These ports do not depend on X11 libraries (i.e. x11* devices
are not available). USES=ghostscript will set dependency on
one of them depending on GHOSTSCRIPT_DEFAULT.
The default device is set to "display" or "bbox".
* print/ghostscript{7,8,9,9-agpl}-x11
Installs a shared library which provides X11 support to
the installed Ghostscript binaries. x11* devices will be
enabled when the library is available.
This depends on *-base (RUN_DEPENDS). USES=ghostscript:x11
will set dependency on one of them.
- Fix integer overflow reported as CVE-2015-3228.
- Update Uses/ghostscript.mk:
* Add x11 keyword. nox11 keyword is now obsolete.
* Use packagename in *_DEPENDS line to prevent relationship between
-base and -x11 packages from being broken.
- Fix x11/nox11 keyword and bump PORTREVISION in ports using
USES=ghostscript to update dependency of pre-compiled packages.
