This is a bit misleading - this has nothing to do with X11 per-se.
What Apple did is something far more awful - they set DISPLAY by
default to a special service that attempts to start X11 automatically
when a connection is initiated. This is a matter of taste, but I must
say that I'm not fond of that change, because I don't want X11 on by
default (just remember the CRAN mirror selection - terrible in Tcl/Tk
no keyboard interaction, but very easy to choose in the CL).
Fortunately you can fix that in your startup scripts.

Please read my previous post on the list about R and Leopard, it has
the fix. (For R CMD SHLIB it's as easy as PKG_LIBS=-mmacosx-version-
min=10.4 R CMD SHLIB).

I works for me flawlessly (on the last seed). Are sure you have
installed X11 and Xcode properly?
In any case please post the relevant parts of config.log (or send me
the whole thing if you wish).
