Solved Error loading nVidia FreeBSD 10.3

I installed x11/nvidia-driver-340 (this is the version for my video card nVidia GT220). However when I try to load it
kldload nvidia
I get this error
KLD nVidia:ko: depends on kernel - not available or version mismatch
linker_load_file: Unsupported file type
I tried to rebuild the port but I get always the same error. kldstat shows that nvidia.ko is not loaded.
Build it from ports. It's a kernel module and it needs to be build against the exact version you have.
I used subversion to download sources
svnlite checkout /usr/src
Maybe I should use instead
svnlite checkout /usr/src?
Thanks for the help, the handbook is not really clear in this, I will try again to install the driver after it finishes checkout
