Yes. The fix from Paul Vojta (TargetFont exch instead of TargetFont in file
render.ps line 193, version 1.9 of gsftopk) did not work for me, although
I thought it did for some time ...

With the fix, I get:
  te.users(gauss)534: gsftopk ptmr8r 600
  gsftopk version 1.9
  [1gs: Error: /typecheck in --makefont--

  gs:    --dict:595/631--   --dict:0/20--   --dict:59/200--

I am using gs3.33. Does the fix work for gs-3.12?

If I use an unpatched version of render.ps, the pk-file ptmr8r.600pk is 
generated, but it is not reencoded.

Well, ps2pk needs .afm files which do not come along with .gsf fonts.
But, I tried a .afm file I found on CTAN and got:

  te.users(gauss)541: ps2pk -v -X600 -R600   -e 8r.enc ptmr.gsf ptmr8r.600pk
  Loading CharMetrics from ptmr.afm and encoding vector from 8r.enc ...
  FontName Times-Roman; Encoding TeXBase
  Checking ptmr.gsf font ... done
  Creating character glyphs for ptmr.gsf ...Floating point exception

If I use Times-Roman.pfa (available on our SUNs), ps2pk goes well.

Thank you, Karl, for the info.
