[OS X Emacs] latex + dvips + ps2pdf from Aquamacs

I tried the following, in the *scratch* buffer of Aquamacs, but they do not
produce anything visible by me in "scratch":

(getenv "PATH") ctrl-J
getenv "PATH" ctrl-J

The "man getenv" gives the following syntax:
getenv(const char *name);

The problem continues from Aquamacs. But ps2pdf runs ok from Terminal.

Best Regards,
