Install packages with just what is needed

[anlarye]

Thank you Gordon.

Your reply has been the most helpful. Some of the others have been outright
insulting. I have installed from source in the past when I couldn't even
find a package in a repository for something I wanted.

And yes it might take more work and more space to build it from source than
using the package in the repository. I'm not really concerned with space or
work. So I will just have to decide which path I'm going to take on this.
