The package ClunkClunk was making worked without any other installpkg's. I'm fairly knowledgeable using Linux, but it's a life long learning process. Any suggestion is appreciated.
In regard to the second part of your post, the reason it's failing is that you don't have the required dependencies to run Handbrake.
Run the following to see the dependencies and whether or not you have them:
ldd /usr/bin/HandBrakeCLI
libfontconfig.so.1 can be found in the fontconfig package which can be found here:
http://slackbuilds.org/mirror/slackware/slackware-current/slackware/x/fontconfig-2.9.0-i486-1.txz
If you post the output of ldd, I can let you know where to get the other files.
