You might try uninstalling that package and then start from Square #1, using Milhouse's install that is at the beginning of the thread. Doing that, there should be no errors.

I set mine up before Milhouse posted this tutorial, but I followed the directions that trevarthan originally posted on the Kagu site. I followed them exactly in the order they were listed, and I had no problems, although I also got a bit stuck like you when I had to install wget.
