Like yourself I know enough to be dangerous so I assume you have rootsh installed.

When you attempt to install the deb from the first post in this thread it fails and on one of the info tabs it lists the missing packages it needs. For me it was three packages whose names I forget save that two of them started with python2.4 and the other started with hildon.

So I logged in as root i.e. sudo gainroot in Xterm and then typed:

• apt-get install <type missing package name here> (for each of the three missing packages)
• answered Y at the prompts

and, voila, when I then tryed to install the pybattery deb it installed .

There's some info here on what apt-get does.

P.S.
Thanks to the OP. This is a very handy app and greatly improves on the default battery indicator .
