looks like it is better.

ok. I'm going to write a bug report. w&s.

Well it is good news :) but even At revision 4786, I get this:
libraries umfpack not found in /usr/lib
UMFPACK sparse solver (http://www.cise.ufl.edu/research/sparse/umfpack/)
not found. Directories to search for the libraries can be specified
numpy/distutils/site.cfg file (section [umfpack]) or by setting
the UMFPACK environment variable.
on anorther 8.04 (and not 8.10) ubuntu.

Except if you have installed libsuiteparse- 3.1.0
You also need g++ don't you?
On my cucrrent install of 8.10, I cannot install libatlas3gf-sse2 but
only libatlas3gf-base but it is only a beta.
scipy is a pretty uncommon piece of software, it is a scientific one :)
All the guys using scipy I know are using the svn version because they
*need* *this* so nice feature.
Quite often, they also need to look at the scipy source to see how good
an optimization algorithm can be it.
Sometimes they even have to hack the code to fit there needs (I did it...)
Scipy is so nice because it is powerfull and open source. All the users
I know (except maybe one ;)) want to be able to compile the svn but they
don't really like to play with system administration.
That is why I think we should have a very easy and accurate procedure to
install scipy on ubuntu 8.10 (I could test on suse if I have time).
