no!
it exits a file called addon*.tar.bz2!!
this will after installation gone! thats right!!!
after "uncompressing addon" you'll find usr/local/keys!!!
you can get the correct file from
here
you have nothing to do with this file, NO renaming, NO unpacking!! the only thing you had to do is downloading and following instructions!
download them, put it into folder /usr/local/etc
power off, power on via remote and so on!!
trust me it works on sf-image 10.07!!
best regards...
