This one I can shed some light on. If you start emacs (or any other program) from a shell (running in a terminal window), it inherits that shell's PATH. If you start it from the finder, though, it doesn't. One way to fix this is to start emacs from a terminal window. Another is to try a hack such as the one you describe. Another one is to explicitly specify the path in the command that runs racket. > > So I tried to compile racket from source.

Can you tell me why you want --enable-xonx? I run racket every day on an OS X box without issue. Is it actually important that it run under X? John Clements
