Compile failure on OSX

I am trying to compile R-2.1.1 on MacOSX 10.3.9, but the make is failing (I
am building it without all the aqua stuff):

./configure --enable-R-shlib --with-lapac

That's incorrect.  Please follow the advice in the R-admin.html file which 
the INSTALL file does ask you to read if you have any problems.  It says 
for your OS:

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

   The last option @option{--with-aqua} is needed only if you want a
   Console GUI. The first two options are strongly recommended.
                                          ^^^^^^^^^^^^^^^^^^^^

It also warns you against using --with-lapack if you don't know what you 
are doing.

make

.... Snip .....
