I've built an OS/2 binary of Ghosctscript 8.63 and it's available from my site at http://os2ports.smedley.info
This has been tested both with CUPS and with GSView.
Cheers,
Paul.

Subject: [gs-devel] GPL Ghostcript 8.63 and GhostPDL 1.53 released
Date: Fri, 1 Aug 2008 13:45:13 -0700
From: Ralph Giles
Artifex Software, Inc. is pleased to announce the release of GPL
Ghostscript 8.63.
This is the fourth scheduled release in the stable Ghostscipt 8.6x
series. It corresponds to the 1.53 release of GhostPDL.
Approximately 238 bugs have been fixed since version 8.62. Of
particular note are robustness and performance improvements with large
files, invalid PDF, and font handling. The ghostpdl release features
improved XPS to PDF conversion as well as a number of other bug fixes.
The major new feature of this release is multithreaded rendering. This
can be requested by passing -dNumRenderingThreads=n on the command
line. The input document is first parsed, and then each page is split
into n bands which are rendered concurrently. This can provide a
significant reduction in processing time on multi-core systems.
Images are now always interpolated in their source colorspace. This
improves correctness for XPS documents and avoids bypassing the custom
color management callbacks for interpolated images. Interpolation and
color management are both expensive operations, so this affects
performance with large images. The effect can be positive or negative
depending on the file and the target resolution. If performance is a
problem, we suggest running with -dNOINTERPOLATION.
Support for OpenPrinting Vector devices has been upgraded to version 1.0.
There are two new devices in this release, both experimental. Behdad
Esfahbod has contributed a cairo output device which uses the cairo
graphics library to generate PDF, SVG, EPS, or PNG files, based on the
requested filename extension. The svgwrite device directly outputs
Scalable Vector Graphics, the W3C XML vector graphics format. Both
support only vector art at this point; text and images will not be
represented efficiently.
Incompatible changes in this release:
The maximum number of color components has been reduced to 8 (from
252) as a performance improvement. Eight is the largest number
commonly used and the largest number for which we support continuous
tone images. Users with special needs can restore the previous
behavior by setting the GS_CLIENT_COLOR_MAX_COMPONENTS preprocessor
symbol to the required number of components at compile time.
The -Z: debugging option now uses 'realtime' instead of 'usertime'
when reporting timing information on unix-like systems. This has
always been the case on windows-like systems.
Obsolete makefiles for the DesqView environment have been removed.
Thanks to everyone whose hard work made this release possible!
