same here :(

Well I would like to have the feedback of the developers on the best
way to fix the auto-detection.
site.cfg should not be needed here.

I do not need umfpack but my goal is to perform a scipy installation
with all the libs users could need.
I should be the same for 32 and 64 using 8.10 but I have to check that
(with kvm it should be easy)
My plan is to provide an installation procedure *without an hand
Ubuntu is going to release 8.10 end of october. It would be nice to have
a standard way to compile the svn on this "intrepid ibex".
Of course, the simplest way to having something working is apt-get
install python-scipy. The drawback with these nice packages it that you
cannot ask for patch or test a new feature.
If someone wants to write a procedure to compile a full optimized scipy
using ATLAS on 8.10 , he's really welcome :)
