No, there is not, that was a cut-n-paste error.

If I am in /Users/mahan/src/PPP/ppp-master/pppd and attempt to open
sys-linux.c, it opens an emacs window, but nothing is present.  If I look
at the buffers window -

.%* *Messages*              695 Messages
    sys-linux.c               0 C/*l             ~/sys-linux.c
    *scratch*               144 Lisp Interaction

It shows up as being in my home directory.

Thanks!  That was a good suggestion.  I was using the Mac OS X 'open'
command which is probably, as you suggested, not picking up the correct
environment, though oddly it is picking up the PATH correctly.

This was something I took from another user on a mailing list.

Dropping the 'open' and invoking Emacs directly fixes that issue!
