Success! Thanks hugely to Dwaine in BMD tech support, after dozens of back & forth emails troubleshooting my issue over the course of several days, it ends up that the new NVIDIA CUDA 5.0.36 drivers (released over the past weekend) finally installed on my MacBook Pro 17" (early 2010 model) running Mac OS X 10.8.2 ML without errors.
More importantly, not only did CUDA install w/o errors for the first time on my machine, but I'm able to launch Davinci Resolve (including 9.0.1) w/o errors, too!
Dwaine & I tried "everything", including his instructing me how to delete CUDA manually (file by file), setting permissions manually using Terminal, my re-installing Mac OS X 10.8.2 ML, and more. Unfortunately, none of those things made any difference, because as it ended up, all along it was a problem with NVIDIA's driver!
The weird thing about this was that other users, including at least one BMD employee, were able to run the software (same Mac OS, CUDA & Resolve versions) on
identical hardware.
This morning, just before I was about to pull the 3rd prty RAM out of my machine (to test if this issue was possibly caused by bad RAM hardware), Dwaine emailed me about the new CUDA 5.0.36 drivers.

I can't thank Dwaine and BMD enough for the above-and-beyond support they gave me. Now I'm finally able to begin learning how to use Resolve!
Cheers!
