6.0-today kernel build fails over nvidia-driver

I was updating from BETA1 and have nvidia enabled in loader.conf. It used to 
be that I had to rebuild from the port after installworld, but now apparently 
the idea is that it gets pulled in during makekernel. I can't see where 
though. The problem seems to be a misquote or a shell-expansion thing.
