You don't need that at all - in fact you don't need any of the gfortran above to run R - it's only needed if you want to install packages from sources that contain Fortran code and then gfortran 4.2.3 is enough.  If you just want to run R then the R*.pkg is all you need.

I've got this G5 2nd hand back in 2011, and unfortunately the Leopard dvd I've got can only install a previous (3.1.0 ... I guess, but I should check) version, and from the Apple website linked at r-project.org there's apparently no way to download older versions of XCode...

Unfortunately we don't have working G5 box anymore (the last one died which we had to pul the plug), so I can't check. But it seems as if you may have more recent non-ppc version installed as well so it prevents the older ppc-verison to install. Please run

file /Library/Frameworks/R.framework/Versions/2.15/Resources/lib/libR.dylib

You should see something like
$ file /Library/Frameworks/R.framework/Versions/2.15/Resources/lib/libR.dylib
/Library/Frameworks/R.framework/Versions/2.15/Resources/lib/libR.dylib: Mach-O universal binary with 3 architectures
/Library/Frameworks/R.framework/Versions/2.15/Resources/lib/libR.dylib (for architecture ppc7400):	Mach-O dynamically linked shared library ppc
/Library/Frameworks/R.framework/Versions/2.15/Resources/lib/libR.dylib (for architecture x86_64):	Mach-O 64-bit dynamically linked shared library x86_64
/Library/Frameworks/R.framework/Versions/2.15/Resources/lib/libR.dylib (for architecture i386):	Mach-O dynamically linked shared library i386

If not, try 
rm -rf /Library/Frameworks/R.framework
and re-installing R.

If all fails, run something like
curl http://r.research.att.com/R-2.15.0-leopard-universal.tar.gz | tar fvxz - -C /

which will simply put the framework in place.

Cheers,
Simon
