Bug has been reported as solved and a new version of ghostscript has recently 
been released that incorparates the fix. I’m happy to volunteer testing a new 
(Mac OS X) binary with Ghostscript 9.21 packaged, but I’ve failed all attempts 
to get a local running GUB build to get a cross-platform build delivering me a 
Mac binary to try out.
