Recompiling is not my bag, yet.

Here's the results, I'm sure I blew my OS.  Fortunately, I have a whole nother 80 gb drive with a complete install of Ubuntu Server 8.10, I can just swap it out, if need be...

You would have to download the source code and change that line in it and recompile it.

But that is the good thing about apt-get/aptitude.  We can just change our repositories and see what it would what to install.  I would rather do that then try and recompile/hack some stuff.
