What is that?!? That's not an Apple compiler and it's broken as you  
can see from the config.log:
It's the GNU C compiler version 3.3.4.

This just means it doesn't support -framework.  This is actually the  
answer to my original question.  Apparently -framework is supported  
in stock gcc 4.x.
You should definitely use Apple's compiler, stock GNU gcc is NOT  
the same as Apple, because there are many features that Apple folks  
have added. You should check out the Apple branch from GNU.
It might not be such a good idea to be too dependent on Apple's gcc.   
There are compilers from IBM and Intel that people may at some time  
be interested in using.

You're free to, but then you should know what you're doing and find  
out the right flags for your compiler ;).

As of R-devel configure will automatically use vecLib if the compiler  
supports -framework and vecLib is present, so you don't need to  
supply any flags unless you have an esoteric compiler.

Cheers,

mmh, gcc 3.3.x from Apple supports -framework and it is documented in  
the gcc man pages. (If I remember well, this is also supported on  
some Win32 version of gcc)

in this case, you need to bypass configure by specifying --with- 
blas=path_to_your_blas_lib
  so gcc won't try to use the -framework flag.
This is of course the same you do on other unices.
You should also want to remove from the configure flags the options  
to build R as a framework and just set --enable-shlib

In the end, given that you are using gcc-dp (darwin ports?) you  
should also run make check after building R to assess the reliability  
of your build.

Please, let us know your progresses here, we can put notes on the R  
for OS X FAQ.
I understand your idea of a "pure" darwin (i.e.not necessarily aqua &  
core foundation based) build, but I strongly believe that a "out-of- 
the-box" configure and build on OS X must rely on apple's tools as  
well on open source tools as much as possible (and IBM compilers  
aren't for free at the moment)

'./configure --help' doesn't mention --enable-shlib.  Did you mean -- 
enable-R-shlib?

Will do.

I just checked and the IBM compilers do support -framework.  It looks  
like the moral is turning out to be if you want to build R on macosx  
you need a compiler that supports -framework.

yes, I apologize

you should specify

--enable-R-framework=no  --enable-R-shlib

as I said, you can live without the -framework flag but you need to  
specify the path or other flags for your compiler,
see e.g. sec A.2.2 Linear algebra in R admin manual
