Well, near as I can tell from your question, you have some python component missing, and some program needs it.

Anyway, Python is a coding language. Like Perl, Ruby, C, C++, Qt, etc. Python is one of those languages that, as I understand it, doesn't need to be compiled to run, so long as you have the requisite interpreter stuff installed. Python isn't really a 'program', it's the coding language, and the requisite 'libraries' that the language uses to translate the human-readable lines of code into stuff to actually execute.

Most likely, you have some sort of dependency problem - meaning, you're trying to install a program that requires Python, but doesn't specify Python as it's dependency, or the right Python package isn't in the repository, or some bug is occuring preventing the proper Python packages from downloading, etc.

In order to get actually useful help though, you need to tell us what specifically you're trying to install, and what kind of error messages you're getting.
