The problem is that the answer to the latter is "no". Apple's branch
has broken gfortran a while ago. So right now there are basically two
alternatives - use old Apple-branch gfortran or use the FSF build (I
tried to port FSF changes to Apple's build but failed - anyone who
succeeded, please let me know).
For the latest optimized R (ppc64) I am currently using complete FSF
build of gcc off the 4.0.x branch and it works fine. In fact the
upcoming R 2.2.1 release for Intel Macs (due sometime next week) is
also built using those tools.
As for the 5224 and Xode 2.2, I don't know about the compatibility,
because I have only one box with Xcode 2.2 due to all the issues it
was causing and that one is already heavily infested with various
builds of gfortran so frankly I can't tell. With the 5224 you'll also
lose the ability to compile i386 code, because those are not "fat"
compilers (but AFAIK three is no gfortran that would support fat
builds anyway). I can package my latest FSF gcc build for anyone
interested... I have it in a separate directory so it doesn't
conflict with the 'regular' tools.
