Just download the debian packages from that website you find when using google.

@jflatt:
I tried to compile your preenv with and without my changes but I can't get it compile. Do I need a special environment like scratchbox from maemo sdk? I tried it there too with same results.

You can view my changes here: https://gitorious.org/~xengi/preenv/xengis-jflatts-preenv/blobs/master/libsdlpre/sdlgl.c#line332
