better diagnostics #10
fall back on asking for the wheezy (stable) version if Percona doesn't have a build for our Debian, which it won't unless we're actually on wheezy or the previous stable, squeeze.
... but that's not working so well for me, but I don't know if it's just because my Debian isn't fresh enough.  seriously, this thing shits itself faster than Windows 3.11.
when doing the apt-get install, exit out of curses windowing entirely and wait for a keypress before going back in so that I can see the vomit produced by trying to
something with Debian's package manager.
add some more random robust error checking somewhere where it doesn't really matter for the purposes of this failure.
