Thanks for your reply, Steve.

I built and installed Click with these commands.
$ ./configure --prefix=/usr/local --enable-all-elements
$ make
# make install

So, I think, I didn't port tkenel module over to FreeBSD.
If I want to that, I need to build click with "--enable-bsdmodule"
option, is it right?

Regards.
