I primarily use (Plain) TeX, but when I looked for help in FAQs and mailing lists, the answers I found were specific to LaTeX.  So I downloaded a pstricks example file from TUG that uses LaTeX, and that doesn't work either.  Even after I put

The relevant error message is "/usr/texbin/simpdftex: line 495: ps2pdf13: command not found"
It tells you that it can't find the ps2pdf13 command.
This should live in /usr/local/bin. 

Open a Terminal window, type "which ps2pdf13" (without the quotes) and hit return. Which of the three possibilitues below do you get? 
(A) /usr/local/bin/ps2pdf13; (B) some other path; or (C) ps2pdf13: command not found

If you get (C), it is likely that ghostscript is not installed.
