Hi Andrew,

first thanks a lot for your effort - I am certain it
will be very much appreciated!

Alright, let's start with the first question:
We are still running debian sarge and therefore would have to
build the above from source.
I used the following steps:
- put
    deb-src http://sefton.astraw.com/ubuntu/ dapper/
  into /etc/apt/sources.list
- apt-get update  # update the source package search list
- apt-get source python-numpy
- cd python-numpy-0.9.8/
  dpkg-buildpackage -rfakeroot

and get:

dpkg-buildpackage: source package is python-numpy
dpkg-buildpackage: source version is 0.9.8-0ads1
dpkg-buildpackage: source maintainer is Andrew Straw <strawman at astraw.com>
dpkg-buildpackage: host architecture is i386
dpkg-checkbuilddeps: Unmet build dependencies: cdbs (>= 0.4.23-1.1)
build-essential python2.4-dev python-setuptools (>= 0.6b2)
python2.3-setuptools (>= 0.6b2) python2.4-setuptools (>= 0.6b2)
dpkg-checkbuilddeps: Build conflicts: atlas3-base
dpkg-buildpackage: Build dependencies/conflicts unsatisfied; aborting.
dpkg-buildpackage: (Use -d flag to override.)

What worries me is
a) the Build conflicts: atlas3-base
b) and the python2.3-dev *and* python2.4-dev dependency
Clearly, python-setuptools and cdbs are not yet installed
on my system (should be no problem).

yes - that would be brilliant!

What about scipy: presently debian sarge comes with
scipy 0.3.2. Installing old-scipy and new-scipy side-by side
seems impossible (unless one does something like wxversion select
stuff...) - should the new scipy debs just replace the old ones?

Best, Arnd
