Hm dunno. You might want to try a search here to see if there's a better answer.
Looks like that message is coming from conftest.sh, which just does a sanity check on your system and sets up the proper makefile depending on the kernel version or such.
This message is displayed when the 'conftest' binary isn't created, which could be a compiler error (missing include?).
I think you could just 'ln -s Makefile.nvidia Makefile', then run 'make'.
