Thanks a lot, that was very helpful.
On a side note I am surprised to see that R-devel's configure script
picks up
/usr/local/bin/gfortran-4.2
instead of
/usr/bin/gfortran-4.2
even though /usr/bin is ahead of /usr/local/bin in my path. Is that an
autoconf setting, that /usr/local/bin is always first, or is it an R
thing or?
Here is my path
kasper-hansens-macbook:~/Source/R-devel/> echo $PATH
/Users/khansen/Bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/
texbin:/usr/X11/bin
and here is a relevant snippet from config.log
PATH: /usr/X11/bin
PATH: /usr/local/bin
PATH: /Users/khansen/Bin
PATH: /usr/bin
PATH: /bin
PATH: /usr/sbin
PATH: /sbin
PATH: /usr/local/bin
PATH: /usr/texbin
PATH: /usr/X11/bin
PATH: /usr/local/bin
It seems like /usr/X11/bin and /usr/local/bin is prepended to the PATH
setting/

Despite reading the "tools" and "building" pages on
r.research.att.com I am still confused. The comment on GCC 4.2 on
the "building" page seems to indicate that I should look under the
"Alternative" section on "tools".
Here I see gfortran-42.pkg which has a build of 5531. But my
version(s) of GCC are
kasper-hansens-macbook:~/Work/packages/> gcc --version
i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5484)

and at the top of the page I see gfortran-4.2.3.pkg which seems to
be a later version (but has no build information).
So which one should I use?
gfortran-42.pkg complements Apple's gcc-4.2 compiler so if you have
Apple's gcc-4.2 then that is the way to go.
I don't see "gfortran-4.2.3.pkg" on the page, but there is
"gfortran-4.2.3.dmg" which is a pure GNU Fortran (thus it doesn't
have any Apple build number) living in /usr/local, independent of
the Apple compilers. That is what we supply with R since we cannot
rely on gcc-4.2 (until recently it was not available to the public).
Also it lives in /usr/local to be fully independent.
As for the build numbers - Apple is very slow in releasing sources
for their binaries, so the current build is usually not available.
(Apparently they have put 5564 up just a few days ago, so I'll build
the updated version soon, but if you're using just the gfortran part
there will be likely no changes sine the Fortran sources come from
FSF).
Cheers,
Simon
