I will?

Sorry, I've never bothered to recompile svn or python or many other things that my Linux install comes with. And I've use them every single day. For money. To feed my face hole.

Yes, when the time comes I can recompile anything on Ubuntu, but you know what? I'll take their already existing package, add patches, and easily create a .deb I can distribute among all the machines I use. Based on the existing package, with existing Ubuntu patches added that fix existing problems for me. Rather than going from scratch all alone in Solaris land.

For the purposes of this discussion nothing you've mentioned falls under the serious banner. I mean no snark at all in saying that - just that those with half a dozen 12 CPU boxes packed with nearly 200Gb of RAM tend to be cutting their own path.
