{{{

libatlas.a libcblas.a libf77blas.a liblapack.a
libatlas.so libcblas.so libf77blas.so

I'm not convinced we need '''any''' shared libraries. I don't believe
ATLAS builds any, and certainly Mathematica comes with libatlas.a, but no
libatlas.so.
Note there is no {{{liblapack.so}}}, yet this builds fine.
On the 64-bit version,
{{{
drkirkby@hawk:~$ ls /ATLAS64/lib
libatlas.a libcblas.a libf77blas.a
libatlas.so libcblas.so libf77blas.so
}}}
but I must have omitted to copy {{{liblapack.a}}} there, which is why I
had to build ATLAS from scratch, which takes about 15 minutes on this
machine in 64-bit mode, but a few hours in 32-bit mode, since the ATLAS
package does not have the right tuning parameters for 32-bit code.
I've since copied the 64-bit liblapack.a to my global installation
directory, so now the directory has
{{{
drkirkby@hawk:~/pre-release/64/sage-4.7.alpha1/local/lib$ ls /ATLAS64/lib
libatlas.a libcblas.a libf77blas.a liblapack.a
libatlas.so libcblas.so libf77blas.so
}}}
which is the same number and names as the 32-bit version.
