The path form Aquamacs is a bit strange. I’m puzzled: I don’t see /usr/local/bin in it. Aquamacs should add to the path, not replace it, I think. 

To understand what’s going on, what is the PATH value in Terminal, and what is your shell?

echo $PATH
echo $SHELL

Bettery yet, run:

dscl . -read /Users/<yourusername> UserShell

In both cases, even with Dick Koch’s version of Ghostscript, the binary should be in /usr/local/bin. If you run

which gs

or 

type gs

in your Terminal we can confirm it. (I can’t because I install ghostscript in /opt myself.) If that’s the case, with the path that Aquamacs reports, it can’t find ps2pdf.
