this is because there is no script hobbitclient-gnu/kfreebsd.sh  in the 
~hobbit/client/bin directory.

as written in the hobbitclient.sh script, you can define you own 
bbosscript with the $BBOSSCRIPT.

/if test "$BBOSSCRIPT" = ""; then
        BBOSSCRIPT="hobbitclient-`uname -s | tr '[A-Z]' '[a-z]'`.sh"
fi
/
the difficulty is that the uname -o output contains a / character.

I already created a custom script for a freebsd based distro, and simply 
creating
the client script was enough.

hope this'll help.
