[Rd] R-1.9.0 won't compile on OSX (PR#6848)

[Prof Brian Ripley]

I don't think this is a bug in *R*, especially as you appear to be using 
the unreleased gcc 3.4!

Hint: there needs to be a dynamic library for libg2c, not a static one. If
there is not, that's a g77 on MacOS X problem, which at one time (gcc 3.1)
we had to overcome by using vecLib.

See the R-admin manual which says

  ./configure --with-blas='-framework vecLib' --with-lapack --with-aqua 

  The first two options are strongly recommended. 

Did you actually follow that advice?  You appear to be trying to use 
atlas, and there is advice about needing a PIC version for that to work.
