Through macports and subversion, I was able to downgrade IM to version 6.8.0 and GS to 9.4 (but all the older builds failed for some reason). Problem persists. Scratchy white lines still visible. Losing hope...
If anyone has thoughts on getting older Ghostscript versions to work, I'll try that. Otherwise, I may have to start learning python.
