The problem is not that I don't know how and where to define PATH
but that my definition of PATH is not found/used by emacs23.
So find out the precise mechanism by which GNU Emacs gets launched!
In my GNU Emacs 23.4 exec-path is $PATH +
"/usr/local/libexec/emacs/23.4/x86_64-apple-darwin10.8.0".
Have you tried to launch GNU Emacs with -Q, i.e., without any customisation?
And also with -q, which means only system-wide customisation? Any differences?
What is the difference to the value when GNU Emacs is launched the usual way?
