 > Ok, that's funny, since LAPACK was used for the compilation (you can see
 it since the show_config is the same than before), although doing
 LAPACK=None should have disabled it. So basically, it should not have
 changed anything... The fact that it worked tends to show that LAPACK
 itself is not the problem, though.

 Hm...So I've used a 1.0.3.1 version compiled on PLD builders and shipped
 by the distro. The 1.0.4 I've used and failed with was compiled *locally
 by me*. The version that works is *also compiled locally 1.0.4* but with
 the LAPACK=None line in front. So that's totally strange...

 > So it would seem that the packaged numpy is the problem, for some
 reason. Which source did you use ? 1.0.4 or SVN ?

 As stated above, I'm using 1.0.4 in both cases (the one without
 LAPACK=None that didn't work, and the one You suggested).
