Yes.

Edit your src/paths.h file in your emacs distribution like this:

#define PATH_LOADSEARCH "/usr/local/src/gnu/dist-18.53/lisp:/usr/local/src/gnu/emacs-lisp"

This, and EMACSLOADPATH, are interpreted just like PATH environment
variable strings, with each path separated by a colon.  They are read
as emacs starts up and are converted into the load-path lisp object,
which is a list.

I've only tried this on 18.53

> Please email replies.

I had a helluva time trying to find out how to do this too, so I
thought others might be interested.  I finally found a function called
decode_env_path in src/emacs.c.
