scipy is misbuilt on os x

[was]

Importing linsolve breaks on os x right now (I've removed the test that exposes this for sage-2.8.8, but want this fixed.

From Josh:

Thats odd, I have a sage-2.8.2 on OSX where all the commands in
numerical/test.py work fine.

Did something change in the scipy package to make it use umfpack for
sparse stuff. By default it uses superlu, but it can use umfpack.

Only think I can think of at the moment, did the order of scipy and cvxopt
change, cvxopt builds umfpack, but scipy was building before cvxopt so
wasn't using cvxopt's umfpack.

What is the current status of this?

On a fresh install based on 2.8.13.rc1, I cannot duplicate this bug. Since I never could, could someone else using OSX verify that

from scipy import linsolve from scipy import sparse

do not raise exceptions so we can close this bug.

it also work for me with 2.8.13.rc2 on a G4 on 10.4, so close this.
