Running any example with PyCUDA results in:

% python hello_gpu.py
Traceback (most recent call last):
  File "hello_gpu.py", line 12, in <module>
    mod = SourceModule(open("hello_gpu.cu").read())

nvcc fatal   : Path to libdevice library not specified

nvidia-cuda toolkit 5.0.35-7 works fine. I'm not sure if this is on
PyCUDA or nvidia-cuda-toolkit's side. Apologies in advance if it's
