R devel - Sep 2009 - Snow leopard ./configure "cannot compile a simple Fortran program"

I hope this is the place for this...

I have to rebuild from scratch under Snow Leopard, and when I  
attempted to build R-2.9.1, I get the following results from ./ 
configure:

Since this seems to be a 'fortran thing' methinks I should send this  
to Apple as well?

Yes, indeed.

  ^^--- I think you don't have a Fortran compiler. fc is a utility on  
SL that has nothing to do with Fortran and Xcode doesn't include  
Fortran, either. Please install GNU Fortran either from CRAN
http://cran.r-project.org/bin/macosx/tools/
or if you feel brave take the Xcode 3.2 add on from
http://r.research.att.com/gfortran-42-5646.pkg

Also please don't forget to add -arch i386 or -arch x86_64 to the  
compilers when configuring R (see R for Mac FAQ) - the defaults are  
different between gcc (64-bit) and gfortran (32-bit)!

Cheers,
Simon

PS: There is usually no need to compile R from sources on OS X - see
http://r.research.att.com/
for the latest R release in both 32 and 64-bit for Leopard/Snow Leopard.
