OK. Took care of that. The shell seems to be recognizing the correct
PATH this time around.

Checked this as well - it agrees with the PATH I established in the
environment.plist file.

After invoking this in Emacs, it did indeed echo the correct path to
the fsf-gdb executable.

Yes, it does seem to be set to some variable. After reading the gdb
documentation, when Emacs opens
gdb as a sub-routine it apparently opens it with the option "-f", the
fullname option. I am not sure how to
change this behavior in Emacs.

I think I am getting really close!
