[PyCuda] Ongoing install puzzle...

  That's the same issue I had ~2 weeks ago - you are using driver 180.51, but 
CUDA 2.2 requires 185.18.08. *
  cuMemHostAlloc is one of the additional symbols used by CUDA 2.2 (and 
therefore pyCuda expects it)

  So the solution seems either to stick to CUDA 2.1, or install the nvidia 
driver recommended for CUDA 2.2
