[R-SIG-Mac] gfortran question

[Todd A. Johnson]

I've failed so far at getting R 2.6.0 (R-devel) to build as 64-bit on my Mac
Pro under Leopard, but at the moment I don't have time to detail my errors.

The simple question at the moment, since I was wondering if it might impact
building of this and other programs is the 4-architecture binary of gfortran
on the r.research.att.com website.  If you install it and run "file
/usr/local/bin/gfortran-4.2" in the Terminal, it reports a "Mach-O
executable i386" and a "Mach-O executable ppc".

Shouldn't "file" also report a ppc64 and an x86_64 executable if it's for
4-architectures?  That was the case for other programs that I've installed
that were for 4-archs.

Also, could someone please provide:

1)  Date of latest successfully building R-Devel for 64-bit on Leopard.  It
seemed like my errors were different for different dates, so it seemed
possible to me that new additions, irrespective of Leopard issues, to this
alpha development release could cause things to fail...?

2)  working configure commmands (in other words, should I still just be
typing in what's listed for building 64-bit R on Simon's web-site? with
changing "8.8.1" to "9.0.0")

Thank you!

Todd
