[SciPy-user] scipy 0.3.2 ebuild

[Jan-Jan van der Vyver]

Dear Scipy-Users,

I've added an Gentoo ebuild that works for me. It gets compiled without
problems. I am complete noob, I only updated the ebuild (based upon work
by Travis Oliphant?? I think) to get 0.3.2. It might be helpful.

I do, however, get sporadic errors, under iPython, when testing scipy.
Most of the time I get :
----------------------------------------------------------------------
Ran 972 tests in 1.796s

OK


Sometimes :
FAIL: check_cdf
(scipy.stats.distributions.test_distributions.test_fatiguelife)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "<string>", line 10, in check_cdf
AssertionError: D = 0.351919695674; pval = 0.000396083177198; alpha =
0.01
args = (1.0783474814080036,)

----------------------------------------------------------------------
Ran 972 tests in 1.776s

FAILED (failures=1)


Why is this? Is it critical?

MfG,
	Jan-Jan

PS. I'm using the 2.6.8 kernel with SMP and preemptive support.
