[wxPython] wxPython 2.3.2 (Linux) glcanvas

I changed PyOpenGL 2.1.1 to PyOpenGL 1.5.7 (__version__=1.5.6b1),
but wxGLCanvas program in demo.py shows only noisy (OpenGL) window!
And wxPython 2.3.1 works okay.

And wxGTK-2.3.2/samples/opengl/cube/cube.cpp works okay.

What is the difference between wxPython-2.3.2(wxGLCanvas.py) and
wxGTK-2.3.2+cube.cpp?

I wrote wxGTK-2.3.2/samples/opengl/cube/makefile.
diff makefile makefile.unx
