[PyCuda] Where do I define the --prefix installation option?

[Hua Wong]

Sorry to bother again, I managed to pass the 'make' phase but I am now 
stuck in the 'make install' one.

I guess it is using setup.py to install all the files that are made 
during the Make process.

But I doesn't have the root privilege. And when I type python setup.py 
--help, it marks that --prefix option is Ignored.

Where do I precise a custom directory for installation?
