I suspect the GL_ALPHA32F_ARB is responsible. Could you try with
GL_ALPHA_32F instead ? (you'll need to modify the sources).

Hmm, I am not familiar with OpenGL, but for some reason it doesn't
recognize GL_ALPHA_32F :
AttributeError: 'module' object has no attribute 'GL_ALPHA_32F'

Sorry, I meant GL_ALPHA32F

I tried it too, but it still doesn't work:
AttributeError: 'module' object has no attribute 'GL_ALPHA32F'

For some reason constants from OpenGL.raw.GL.ARB.texture_float are not
included in OpenGL.GL namespace on some platforms. Everything works fine
with PyOpengl-3.0.1 on freebsd, but fails on windows with pyopengl 3.0.2a4
(from http://www.lfd.uci.edu/~gohlke/pythonlibs)
One workaround would be to explicitly import
OpenGL.(raw.?)GL.ARB.texture_float and then remove gl. prefix from
GL_ALPHA32F_ARB
