This doesn't make sense to me. Perhaps a missing executable bit, or  
perhaps a missing read bit (otherwise the shell won't find the script  
at all). Post the output of
     ls -l /usr/local/teTeX/bin/powerpc-apple-darwin-current/epstopdf
It should be similar to:
     -rwxr-xr-x   1 root  admin  12387 Feb  6 21:17 [...]/epstopdf
I suspect your system has
     -rwx--x--x   1 [...]
Force correct permissions with
    sudo chmod 755 /usr/local/teTeX/bin/powerpc-apple-darwin-current/ 
epstopdf

The epstopdf package is a stopgap measure to allow pdflatex to  
include eps files. Convert manually to pdf once and use pdflatex from  
then on.

The whole idea is to skip dvips and ghostscript, and epstopdf is  
meant to be used with the _latter_
