Thanks for the details!

That's good to know but no thanks :-) I like being able to update my R devel
in less than 1 min. by downloading the last universal build from
http://r.research.att.com/ (thanks a lot for providing this).
Also, I like being able to use the other universal stuff provided
there (like graphviz-2.8.dmg and glibgtk-bin-1.2.10-univ.tar.gz)
that would then become incompatible with my home made R (compiled
with Xcode's gcc). Is that correct?

Besides, Apple still does not provide a Fortran compiler, do they?
