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!
