Installing wxWidgets and wxPython

Hello. I'm trying to do something that is seemingly simple, but I'm
having no end of problems. I want to get things setup so that I can
compile wxPython from source. I need this because I am planning on
extending wxPython with some widgets of my own. I am running a Gentoo
system, so originally I was using the latest wxWidgets and wxPython
from the portage tree. With this setup, it seemed there was some
version problems, so I decided to unmerge, and build everything from
tarballs.

So I downloaded the wxPython-src-2.7.2.0 tarball and proceeded to try
and get everything installed. I succeeded in installing wxWidgets
using the basic instructions. The problem came when installing
wxPython. I had errors with the "_media" extension. It says:

cannot find -lwx_gtk2_media-2.7
collect2: ld returned 1 exit status

Now, I have found other message board responses about this, and they
all seemed to be about gstreamer. I have the latest gstreamer emerged,
so I don't know why I would still have this problem. Anyway, I
disabled this extension just to see if it would work without it.

I also had problems with glcanvas, stc, and gizmos. When I disabled
all of these, I was able to finally finish compilation. After
installation, it does appear to be working.

Is there something special I have to do when building wxWidgets? It
seems that certain controls just didn't get built. Is there a good
updated guide to getting this all installed properly?

Thanks,
Chris Anderson
