Comment 4 for bug 1402409

I'm not sure how to install the kernel with the bcmwl libraries
installed (I need them to test my wireless don't I).
Naturally, I get the following errors:
"
Error! Bad return status for module build on kernel:
3.18.0-031800-generic (x86_64)
Consult /var/lib/dkms/bcmwl/6.30.223.248+bdcom/build/make.log for more
information.
