Yes, that works much better. Only 2 errors now:

======================================================================
ERROR: check_random (scipy.linalg.basic.test_basic.test_det)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/users/exp/alted/bin-i686//lib/python/scipy/linalg/tests/test_basic.py", line 282, in check_random

----------------------------------------------------------------------

Curiously enough, if I change the directory to scipy/Lib/linalg, start the
python interpreter and run the tests there, everything goes well:

----------------------------------------------------------------------
Ran 600 tests in 1.333s

OK
<unittest.TextTestRunner object at 0xb727e7cc>
-----------

You can note, however, that only 600 tests were executed there.

So, it seems that my ATLAS libraries were bad. Uh, I don't know what I was
doing wrong, but apparently I repeteated the error twice. That's strange
because your instructions in INSTALL.txt were clear enough :-/ Perhaps
something wrong with my software versions?

gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-42)
LAPACK, Version 3.0 (update) Date: May 31, 2000
ATLAS 3.6.0

> Also, do the  following commands work?
> 
> cd Lib/lapack
> python setup_atlas_version.py build_ext --inplace
> python -c 'import atlas_version'

Here you are:

[alted at api linalg]$ python -c 'import atlas_version'

Now, with my own generated ATLAS libs:

[alted at api linalg]$ python -c 'import atlas_version'

At first sigth, I can see a difference: the "-fno-second-underscore" flag
that you put when compiling, while I didn't put this. Can this account for
the problems?

Thanks for your help!
