I'm having problems building matplotlib on windows from a folder from SVN, and haven't done it
before (previously had used the prebuilt binary download).  I don't know what I am doing wrong.
I'm on winXP, Python 2.5. and will be using wxPython with matplotlib as well.

The folder with the contents from SVN I've named matplotlib_svn.  From the cmd line and
while in that directory I wrote

python setup.py build

and got what follows.  I'm not sure what I am to do (regarding finding an appropriate
compiler).  Any help is appreciated.
