If you don't already have BlackBox 0.70.0 on your system, the SlackBuild
script will fail when building BBKeys (missing libbt).

You'll need to build it with this failure, install the resulting package
(thus spamming your system), rebuild using the SlackBuild script, then run 
"upgradepkg --reinstall" on the final package.

(Will someone look into a proper library copy-and-compile method?)
