If you have to ask, you should *NOT* attempt to build this kernel module
on FreeBSD.

The kernel, kernel interfaes, etc. are *DIFFERENT* between Linux and FreeBSD.
signficicant sourte-code changes will VERY PROBABLY be require to get 
the module to (a) compile, and (b) run, in a FreeBSD environment.

To do _that_ -- modifying the sources -- 'where the build directory is' is 
a very _minor_ incidental piece of knowlege.  If you don't have that 
incidental knowledge, is is virtually certain, you don't have the skill set
to do the required source modifications.

Executive summary -- this is a DDT issue.
