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.
