I am primarily using 4.1 but I still have a couple of servers running
3.4, so I want to ensure that I can still build that using Ubuntu
11.10.

Thank you! 22856 did the trick. BTW, I also had to pull in a few more
fixes to get everything to work. I am listing them here in case
someone else runs in to the same issue. The only outstanding problem
is that bringing up a DomU with SDL leaves you with a flickering SDL
window. Using VNC is a workaround for that.
