It's not a fake configure. You have to first install "lapack", then do a configure with the "--with-netlib-lapack=NLAPACKdir/<your lapack library name>" flag, and then simply build by typing "make". If you type configure again without the "--with-netlib-lapack=NLAPACKdir/<your lapack library name>" flag, you will override your previous configuration and build without full lapack support.

But as you have already built lapack and atlas, just follow the instructions from <> to get your fully functional liblapack.a:

mkdir tmp
   cd tmp
   ar x ../liblapack.a
   cp <your LAPACK path & lib> ../liblapack.a
   ar r ../liblapack.a *.o
   cd ..
   rm -rf tmp

Have fun,
