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:
