This is actually for the default variants…
Then, however, the question is why it used -faltivec instead of -msse3
or such on my Mac Pro (x86_64)...

Ah, thanks. I wonder why it doesn't for me. I am using up to date
macports with snow leopard. For me the default variants leads to being
built with atlas. If I specify no_atlas variant then I get the no
external blas shown earlier. I wonder if something has changed
recently to stop building against veclib.
Shall I open a ticket?

Me too

Actually, I don't have ATLAS installed, so that's the difference...

py26-numpy with veclib
Hi,
Is it possible to build py26-numpy against veclib with macports?
I had assumed that specifying +no_atlas variant would fall back to
using veclib (from reading tickets it looks like thats what it did
before) but instead it seems to use no accelerated library. This is
the result of numpy.show_config() when built with +no_atlas:

Note that I am on x86_64, so that looks a bit strange.
