I got it installed and working on Slackware 12.0 a couple of weeks ago. 
Some info below.

You just need to download the large 25MB or so file from wxPython and all 
the other stuff comes with it. I suppose it gets complicated if you have a 
different version of Wxwindows/wxwidgets installed already. Luckily I was 
doing a clean installation.

I agree they are far more complicated than necessary. Seems like very 
minimal effort has been put into making compilation and installation of 
the package simple. FWIW, here are my (simplified) instructions which 
worked for me:

Download combined Wxwidgets/Wxpython package from Wxpython website (approx. 25MB)
Untar and cd into WxwidgetsDir
mkdir bld
cd bld
../configure --enable-optimise --with-opengl
(If you don't enable OpenGL you get problems with the wxPython install later
as it seems to assume OpenGL is enabled...)
make
make -C contrib/src/gizmos
make -C contrib/src/stc
sudo make install
sudo make -C contrib/src/gizmos install
sudo make -C contrib/src/stc install
cd ../wxPython
Edit config.py to say WX_CONFIG = "wx-config" or else warnings about having
only one config environment seem to confuse the next bit
sudo python setup.py install

and that was it. Hope it is useful to someone - meant to post it earlier 
but forgot, sorry.
