I made a wiki entry a while back about how to work around this problem, but it 
looks like someone deleted it in mid-November, and I dont have a backup copy.
My solution requires ghostview and xpdf, which is why we dont include it in 
mpl by default.

You can remove the following block in backend_ps.py, starting around line 
1144:

            command = 'latex -interaction=nonstopmode "%s"' % texfile

            verbose.report(command, 'debug-annoying')
            stdin, stdout, stderr = os.popen3(command)
            verbose.report(stdout.read(), 'debug-annoying')
            verbose.report(stderr.read(), 'helpful')
            command = 'dvips -R -T %fin,%fin -o "%s" "%s"' % (pw, ph, psfile, 
dvifile)
            verbose.report(command, 'debug-annoying')
            stdin, stdout, stderr = os.popen3(command)
            verbose.report(stdout.read(), 'debug-annoying')
            verbose.report(stderr.read(), 'helpful')
            os.remove(epsfile)
            if ext.startswith('.ep'):
                dpi = rcParams['ps.distiller.res']

                if sys.platform == 'win32':
                    command = 'gswin32c -dBATCH -dNOPAUSE -dSAFER -r%d \
                      -sDEVICE=epswrite -dLanguageLevel=2 -dEPSFitPage \
                      -sOutputFile="%s" "%s"'% (dpi, epsfile, psfile)
                else:
                    command = 'gs -dBATCH -dNOPAUSE -dSAFER -r%d \
                    -sDEVICE=epswrite -dLanguageLevel=2 -dEPSFitPage \
                    -sOutputFile="%s" "%s"'% (dpi, epsfile, psfile)

                verbose.report(command, 'debug-annoying')
                stdin, stdout, stderr = os.popen3(command)
                verbose.report(stdout.read(), 'debug-annoying')
                verbose.report(stderr.read(), 'helpful')
                shutil.move(epsfile, outfile)
            else: shutil.move(psfile, outfile)


and replace it with this:

            command = 'latex -interaction=nonstopmode "%s"' % texfile
            verbose.report(command, 'debug-annoying')
            stdin, stdout, stderr = os.popen3(command)
            verbose.report(stdout.read(), 'debug-annoying')
            verbose.report(stderr.read(), 'helpful')
            command = 'dvips -R -T %fin,%fin -o "%s" "%s"' % (pw, ph, psfile, 
dvifile)
            verbose.report(command, 'debug-annoying')
            stdin, stdout, stderr = os.popen3(command)
            verbose.report(stdout.read(), 'debug-annoying')
            verbose.report(stderr.read(), 'helpful')
            os.remove(epsfile)
            pdffile = tmpname + '.pdf'
            if ext.startswith('.ep'):
                command = 'ps2pdf "%s"'% psfile
                os.system(command)
                command = 'pdftops -level2 "%s" "%s"'% (pdffile, psfile)
                os.system(command)
                os.remove(pdffile)
                command = '/usr/local/bin/ps2eps -l "%s"'% psfile
                stdin, stderr = os.popen4(command)
                verbose.report(stderr.read(), 'helpful')
                command = 'epstopdf "%s"'% epsfile
                os.system(command)
                shutil.move(epsfile, outfile)
                shutil.move(pdffile, basename+'.pdf')
            else:
                command = 'ps2pdf "%s" "%s"'% (psfile, pdffile)
                stdin, stderr = os.popen4(command)
                verbose.report(stderr.read(), 'helpful')
                os.remove(psfile)
                command = 'pdftops -paperw %d -paperh %d -level2 "%s" "%s"'% \
                            (int(pw*72), int(ph*72), pdffile, psfile)
                os.system(command)
                shutil.move(psfile, outfile)
