I know someone out there has the answer to this. If I run texexec 
through a shell, even with the full path to texexec, I get an error, 
"/usr/local/teTeX/bin/powerpc-apple-darwin-current/texexec: line 1: 
sed: command not found
`.pl' not found."

Running Google with the error shows that it is quit common, but I could 
not find a good fix. I guess kpsewhich gets lost in the shell because 
the shell needs full paths the whole way through the command. Has 
anyone written a shell to get texexec --pdf ?

Thanks
