[Patch] Fix use_gs for ghostscript >= 8.15.2

[mkent]

Trying out the use_gs option I had to make a slight adjustment to the options passed to ghostscript, seems they removed -o at some point.

This is using the version of ghostscript that ships with CentOS 5.1. Exact version is 'ESP Ghostscript 8.15.2 (2006-04-19)'
