Installing CUDA 2.2 on Mac OSX

Installing CUDA 2.2 on Mac OSX is pretty trivial. Only warning/suggestion: manually remove the CUDA 2.1 SDK directory from /Developer/CUDA
Do a fresh install (always recommended).

I tried upgrading without removing CUDA 2.1 SDK and saw my image denoising project failing to compile. This was the error I saw: "ld: duplicate symbol _cutFree in ../../lib/libcutil.a(cutil.cpp.o)"

My deviceQuery output:

hogwarts:emurelease vivekv$ ./deviceQuery
CUDA Device Query (Runtime API) version (CUDART static linking)
There is no device supporting CUDA.

I shall also post my experience installing CUDA 2.2 on a MacPro running CentOS 64-bit.
