im not that familiar with the mac os x terminal and bash commands. i tried "nvcc -g <filename>" to compile an example but the terminal says "nvcc" is not recognized as a command. now i have successfully run the examples in the SDK so i must have the drivers and the toolkit alright. the only thing that i have done was to change the name of the "GPU computing" folder to "CUDA" since the space in the name of the folder annoys me,
