gfortran binary for Xcode 2.1

Recently Apple released Xcode 2.1 for Mac OS X 10.4 (Tiger). Beside  
i686 support it also features new version of the gcc4 compiler  
collection. The good news is that finally it's possible to add most  
recent gfortran without touching the other system files. I have  
created a small package doing exactly that - see http:// 
wiki.urbanek.info/index.cgi?TigerGCC It contains gfortran apple build  
5202 with both 32-bit and 64-bit support and a small uninstall script  
so you can remove it at any time.

I highly recommend upgrading to Xcode 2.1 for all Tiger users that  
want to compile their own R using gcc4 (such R passes make check, but  
don't forget to add F77=gfortran FLIBS=/usr/lib/libgfortran.a to  
configure). If you use CRAN release of R, you can safely ignore this  
as the CRAN build uses gcc-3.3 and g77 which is still safer for 32- 
bit version of R and compatible with both Tiger and Panther.
