Most of the work was done by Olli, I only added a -lelf
to linking stage.

We did find out that we still lack some important
providers in FreeBSD so some of the examples
won't work but it should still be useful.

BTW, stuff like the NFS provider should not be difficult
to finish but given that our implementation is not
related to the Solaris one it does require at least
adding probes to our code.
Just something to investigate in the future ;).

Cheers,

Pedro.
