No. Just leave things alone if you don't have an accelerated BLAS at hand.

Thanks Robert
I have a deadline and don't have time to install ATLAS. Instead I'm
installing clapack. Is this the corrrect thing to do?

No, you didn't do anything wrong, per se, you just built the reference F77 BLAS.
It's not an accelerated BLAS, so there's no point in using it with numpy.
There's not way you *can
I'm the one who created libblas.a so I must have done something wrong.
This is lapack-3.1.1.

If your BLAS just the reference BLAS, don't bother with _dotblas. It won't be
any faster than the default implementation in numpy. You only get a win if you
are using an accelerated BLAS with the CBLAS interface for C-style row-major
matrices. Your libblas does not seem to be such an accelerated BL

Okay, yes, that's the problem. liblapack depends on libblas. Make sure that you
specify one to use. Follow the d

That's just weird. Can you import numpy.core.multiarray by itself?

Hi
When I try
import numpy
id(numpy.dot) == id(numpy.core.multiarray.dot)
I get True. But I have liblapck.a installed in ~/lib and I put the lines
[DEFAULT]
library_dirs = /home/myeates/lib
include_dirs = /home/myeates/include
in site.cfg
In fact, when I build and run a sytem trace I see that lib
