Using: nvidia-installer ncurses user interface
-> License accepted.
-> No precompiled kernel interface was found to match your kernel; would you li
   ke the installer to attempt to download a kernel interface for your kernel f
   rom the NVIDIA ftp site (ftp://download.nvidia.com)? (Answer: No)
-> No precompiled kernel interface was found to match your kernel; this means
   that the installer will need to compile a new kernel interface.
-> Kernel source path: '/lib/modules/2.6.5/build'
-> Performing cc_version_check with CC="gcc".
