Yes -- legacy support is of course intended...  matplotlib has been 
going for over 10 years, after all, and we're very conservative about 
intentionally breaking legacy systems.

Have you tried setting ps.usedistiller to False, or xpdf?  There have 
been problems using Ghostscript as a distiller with recent versions of 
Ghostscript.

We'll need a minimal example, or at least a copy of the PS file to 
investigate this further, however.  Also, what platform, version of 
matplotlib and Python are you using?
