ups-monitor doesn't contain python-module-pyorbit package in a list of packages
on which this package depends.

I don't feel certain if it's a ups-monitor packaging bug exactly, sorry in advance.

But error disappeared just as I installed python-module-pyorbit package.
Steps to Reproduce:
1. apt-get remove python-module-pyorbit
2. apt-get install ups-monitor
3. run ups-monitor from command line
Actual Results:  
The following error raises:

Fatal Python error: could not import ORBit module
Aborted


Expected Results:  
ups-monitor runs
