Oh, its the compile time place, not the run time. That looks like a bug.

No its not, its /Library/Application Support/Emacs.

That's not the point.  The point is that the Emacs I compile for myself 
should by default ignore site wide stuff in global places.  It should 
require a choice to use it.  On Linux-distributions site lisp always 
looks like a garbage heap full of bad ideas dumped there by who-nows. 
And that's when installing a fresh distribution.

This is not the correct fix.  But we might add something for those that 
want a global site-lisp.  I'll think about it.
