The command causing error looks like "kernel install" command!?!?!
It was long ago when I installed nidswrapper, so many things have been changed. And I always have custom kernel.
So, I only can make guess, apology...
what happens if:
1. you compile your custom kernel?
2. you make clean and make again with ndiswrapper.
Or anything else written in README file??
apologies for not helpful post.
