You need Python, PyQt, and PyKDE. I developed this using 3.7 versions of both PyQt and PyKDE.
If running Gentoo linux see note at bottom.

After you have the required libs installed
To install be root and run:

sh install.sh

yes I need a better install method

To run the application as any user do:

/usr/local/bin/kbbtray.py

If /usr/local/bin is in your path then just 

kbbtray.py

will work
