py27-scipy: unittest linalg / blas / arpack errors

[cdeil (Christoph Deil)]

With py27-scipy @0.11.0_0+gcc45 I see a lot of scipy unit test failures mentioning linalg / blas / arpack : ​https://gist.github.com/3937487

Are these scipy bugs or problems with the Macports scipy build?

Issue #36696 might be related to this issue.

A scipy developer commented that these are all known problems for scipy on Mac OS 10.8: ​https://github.com/scipy/scipy.org-new/pull/5#issuecomment-9993311

Maybe these issues will be resolved with the next scipy version. Would it make sense to have the scipy +atlas variant on by default?

Good to know, thanks for following up.

In the past the +atlas variant has been the source of a lot of problems, hence it being off by default.

Then maybe just close this ticket and we can hope that the next scipy version works without errors on Mac.
