This is exactly how we do it.  And you don't *have* to change the imake
files to get this, either.  Just:
	
	# make install DESTDIR=/usr/X11
	# mv /usr/X11/usr/bin/X11 /usr/X11/bin
	# mv /usr/X11/usr/include/X11 /usr/X11/include
	# mv /usr/X11/usr/lib/X11 /usr/X11/lib
	# mv /usr/X11/usr/lib/*.a /usr/X11/lib

	## clean up
	# rm -r /usr/X11/usr

	## link the directories into /usr
	# ln -s /usr/X11/bin /usr/bin/X11
	# ln -s /usr/X11/include /usr/include/X11
	# ln -s /usr/X11/lib /usr/lib/X11

	## and if you don't want to make everyone do a -L/usr/X11/lib
	# ln -s /usr/X11/lib/*.a /usr/lib

If you can help it, I would highly recomend that you *don't* link all
the libraries into /usr/lib (the last line).  For that matter, I wouldn't
do any of the links into /usr.  Just force everyone to use 
-L/usr/X11/lib -I/usr/X11/include.  Of course, for those of us who have
customers that expect things to always be in the same place...

#ifdef WISH

This does have one problem.  X want to find things (like app-defaults) in
/usr/lib/X11.  This can be changed at compile time, but (as far as I know)
it can't be changed at run time.  It would be trivial to add a XLIBDIR
environment variable that could also be set to /usr/X11/lib.  If fact,
the best thing would be to have a XLIBDIRPATH, that could be set to
a number of directories (separated by colons).

#endif /* WISH */

The really neat thing about this, is that /usr/X11 can be a link to
something else.  This is really nice for trying new releases.
