Compiling numpy with lapack and atlas

Hello,
      I am trying to compile Numpy with lapack & atlas. In site.cfg I put,
[atlas]
library_dirs = /usr/local/lib/atlas/
atlas_libs = cblas, lapack, f77blas, atlas

and installation seems to go well. It says,
  FOUND:
    libraries = ['cblas', 'lapack', 'f77blas', 'atlas']
    library_dirs = ['/usr/local/lib/atlas/']
    language = c
    include_dirs = ['/usr/local/lib/atlas']
and the lines with gcc <something> -lcblas -llapack don't give an error. But
afterwards running,
$ ldd ~/numpy-1.0/build/lib.linux-i686-2.4/numpy/linalg/lapack_lite.so
linux-gate.so.1 =>  (0xffffe000)
libpthread.so.0 => /lib/libpthread.so.0 (0x40238000)
libc.so.6 => /lib/libc.so.6 (0x4028b000)
/lib/ld-linux.so.2 (0x80000000)

which I think means libcblas and libatlas are not linked. Can someone tell me
what's going wrong here?

Thanks,
Abhishek
