Hi, A.S.: Ralf, wasn't the reason why we shifted to Vincent's build machine running 10.5, because numpy didn't run on 10.4 when built on 10.6?

I don't know details. Of course it is contradictory to my above assumtion that the build was carried out on a 10.6 ... > 4) Attempted to run Python and import Pylab.

So I attempted to install from source: Can you give more details on the _tkinter error, is it matplotlib specific, or does it mean the Python _tkinter if such one exists at all? It's kinda strange. > 5) I downloaded matplotlib-1.0.0.tar.gz and untarred it. Then I ran: > 'make' (which supposedly takes care of finding out where all the Mac stuff > is located) and For Python packages, ``make`` is *usually* not used.

You got it. If you have freetype2 and libpng installed on your system, just have a look at setupext.py, and add the installation root path (most likely '/usr/local') to the 'darwin' section. It is left out because of problems on > 10.4, but on your 10.4 system it should work. It's the most easy solution if. If you don't have freetype2 installed / libpng, and you really want to compile from source (if we cannot sort out the _tkinter thingy), then there are two ways: Hard-core installation by compiling them yourself, or assisted by make.osx. I personally cannot give you advice with the more easy make.osx way, but be aware of that also this compiles and installs the libs. For the hard-core way you might find my docs on that useful (it's intended for 10.6, so feedback from 10.4 users is welcome): http://vincentdavis.info/Shared/Docs/matplotlib-installation/build/html/. Vincent is hosting that site, gratefully acknowledged. > As a third try, I attempted to install using easy_install, a tool for > installing Python modules: > 6) I ran 'easy_install matplotlib'.

Btw, the binaries *should* work. It looks like kind of failure of the binaries. Might be that I'm missing something, though.
