Dear Simon,
Thank you for this information.
Now I have installed gfortran-4.2-5564-darwin9.tar.gz on Leopard and
tried to compile ROOT again, but this time I got the following error:
g++ -dynamiclib -single_module -undefined dynamic_lookup -install_name
@rpath/libminicern.so -O2 -m64 -o lib/libminicern.so
misc/minicern/src/cernlib.o -ldl misc/minicern/src/hbook.o
misc/minicern/src/kernlib.o misc/minicern/src/zebra.o libgfortran.dylib
/usr/lib/gcc/i686-apple-darwin9/4.2.1/libgfortranbegin.a
i686-apple-darwin9-g++-4.0.1: libgfortran.dylib: No such file or directory
I know that this is not necessarily an R-related question but I would
greatly appreciate your help if possible (at least it is a Mac- and
somehow a BioC-related question).
When I have tried to compile ROOT with gfortran-4.2.3.dmg I got the
following error:
gfortran -O2 -m64 -o bin/g2root main/src/g2root.o -Llib
lib/libminicern.so
/usr/local/lib/gcc/i686-apple-darwin8/4.2.3/../../../x86_64/libgfortran.dylib
/usr/local/lib/gcc/i686-apple-darwin8/4.2.3/x86_64/libgfortranbegin.a
-lm -Wl,-rpath,@loader_path/../lib -pthread -ldl
ld: -rpath can only be used when targeting Mac OS X 10.5 or later
As you can see gfortran-4.2.3 could find libgfortran.dylib at:
/usr/local/lib/gcc/i686-apple-darwin8/4.2.3/../../../x86_64/libgfortran.dylib
while gfortran-4.2.4 could not find libgfortran.dylib.
Thus maybe I did make a mistake when installing gfortran-4.2.4. Here is
what I did:
$ gunzip gfortran-4.2-5564-darwin9.tar.gz
$ sudo tar -xvf gfortran-4.2-5564-darwin9.tar -C /
$ sudo ln -s /usr/bin/gfortran-4.2 /usr/bin/gfortran
Do you know what I need to do so that libgfortran.dylib can be found?
P.S.:Since many Mac users are no Unix experts please allow me to suggest
to place on your website the commands to install/uninstall gfortran. I
have found the following website, which told me how to install gfortran
and how I could uninstall it:

Thank you in advance.
Best regards
Christian

Dear Simon,
One more question:
I have just unzipped gfortran-4.2-5564-darwin9.tar.gz. The version
gives:
Using built-in specs.
Target: i686-apple-darwin9
Configured with: /Builds/gcc/gcc_42-5564/build/obj/src/configure

Thread model: posix
gcc version 4.2.1 (Apple Inc. build 5564)
This means that this version seems to be older than the one I am
using now?
No, that is GNU Fortran 4.2.4 that I was referring to. The "gcc
version 4.2.1" comes from Apple's Xcode 3.1 gcc-4.2 branch since that
is what they define - it just adds Fortran support to the existing gcc
4.2.1 branch of Apple that you installed as Xcode. However, the
Fortran part is merged from the GNU Fortran 4.2.4 release - hence I
refer to it as 4.2.4.
Cheers,
Simon

Dear all,
I have the following problem:
My Bioconductor package xps requires both R and ROOT, whereby I
compile ROOT usually from source. Until now this has not been a
problem since I do all my development on Tiger. However, now I
wanted to compile ROOT on Leopard but failed since my gfortran
compiler is too old, see:
http://root.cern.ch/phpBB2/viewtopic.php?t=9721&sid=003b01ddb64f33dbe0c74651ee089c34
To solve the problem I should upgrade to the latest version coming
with gcc-4.4 in Fink.
I would advise against that - using gcc from Fink usually calls for
a disaster. The real solution is to fix their flags, but that's
another story ...
Thus my question is:
Can I also use this version for R or do I need to use the version
downloaded from att?
I would recommend using the Leopard gfortran 4.2.4 for Xcode 3.1.x
from the Mac devel page
http://r.research.att.com/tools/
which I assume is what you meant by the latter.
Cheers,
Simon
