compiling R devel on vanilla tiger

Of course now you have R with AquaTcl, your Tcl/Tk based packages
will not work from the Aqua GUI, and packages such as tkrplot will not
work at all.

I just repeat what I've said here already: unless you desperately
need 64-bit R there is no real benefit from using gcc4, because
it's
still very instable (gfortran segfaults even on simple examples)
and
unreliable (gfortran is even slower than g77). There is a good
reason
why the CRAN build uses gcc3 and g77.

That was a nice clear statement. So given that I want to compile R
from source (because I need the devel version), without too much
hassle I should use gcc 3.3 supplied by Xcode 2.1. But what do I do
with respect to the Fortran compiler?

CRAN installer package of R comes with g77 3.4 which is recommended.
You can install it even separately from the R binary (preferably
using sudo installer ... because there is a bug in the package that
doesn't allow non-admins to install it - c.f. the list). That  
version
is tested to work with the gcc3 that cones with Xcode 2.x. If you
plan to compile R from sources you may also want to run
sudo gcc_select 3.3
to prevent having problems with cc_dynamic.

How close should the versions match? Should I get
  - gcc 3.3.6 (latest version of the 3.3 branch) from Gnu's website
  - gcc 3.4.4 from Gnu's website
  - gcc 3.4 from the hpc.sourceforge website

It doesn't really matter as long as it is >=3.3 and <=3.9 except  
that
it should use static Fortran libraries if possible (unfortunately  
the
more recent ones don't).

It works!

So here is what I did:
1) Downloaded the most recent (binary) version of R from cran and
mounted the disk image.
2) installed the g77 compiler from the package by
   sudo installer  -pkg /Volumes/R-2.1.1/Packages/g77.pkg -target /
(if you just want to check the package information, do
   installer -pkg /Volumes/R-2.1.1/Packages/g77.pkg -pkginfo
)
3) compiled R using the flags
./configure --with-aqua \
   --with-blas='-framework vecLib' --with-lapack \
   --with-tcl-config=/Library/Frameworks/Tcl.framework/tclConfig.sh \
   --with-tk-config=/Library/Frameworks/Tk.framework/tkConfig.sh \
   R_PAPERSIZE=letter \
   F77=g77 \
   TCLTK_LIBS='-framework Tcl -framework Tk' \
   TCLTK_CPPFLAGS='-I/Library/Frameworks/Tcl.framework/Headers
                     -I/Library/Frameworks/Tk.frameworks/Headers'
(bad linebreak because of the mail program in the two last lines)

Thanks a lot!
