[Click] Install under FreeBSD 6.3

[G Rogers]

I have been tasked to build Click 1.4.2 for FreeBSD v6.3.  I am new to Click
and FreeBSD.  Extremely new.

The instructions, extracted from the tarball, do not include how to install
for FreeBSD.   When I try, I get the message that the linux source can not
be found and to use the ./configure with the --with-linux=LINUXDIR command.

And there I sit.  I would appreciate any assistance.  Thanks.  -Geri
