I'm not sure compile/link_program actually works in PyOpenCL. It doesn't
have any tests for it, which is probably a sign that it might not. If
you have a little bit of time, I'd appreciate if you could look into it
and submit a patch, ideally with tests. In the case above, I think
changing _prg to_get_prg() might already be enough.
Thanks for the reply. I will take a look at the code and hopefully provide a fix
with some tests when I have a moment.
