[SciPy-user] General question on scipy

Hi,

I am relative new to python, but I would like to use python for
post-processing of data etc. I am using a LINUX machine with python
installed on it, but to use if for scientific analysis and creating pictures
etc. I need to install: matplotlib, numpy, scipy. It was quite difficult to
install matplotlib and compile it against numpy (or something like that),
but now I really would like to have a package that can handle matrix
calculations (e.g. matrix multiplication, singular value decomosition) and
similar. The package then I need to install is: scipy.

So I tried to install scipy, but, as I expected, it does not work (multiple
libraries are not found). The whole error message is attached to the end of
the email.
My question: Why do I need to install additional packages? Isn't it possible
to code them up in scipy and use pure python for this? Or is it for
computational reasons (to put computative intense calculations in C or
whatever)? Or do most of the functions not yet exist in scipy (because its
version 0.XX)? What is the reason for not having an entire-pure-python
extension to python.numpy?

My second question: How to install scipy? What packages are missing? I am
sure I have numpy installed correctly, but I failes installing LAPACK, which
error-message is here:
