Here is a patch to make it complain about not having Xapian *before* starting
the state dump, so it doesn't get to step 3 and suddenly find out that it can't
load Xapian.

Speaking of not having the Xapian gem, when I tried "gem install xapian-full",
it looked like it worked, but didn't actually install a gem on my system. Here's
the build log: http://pastebin.com/f2d25a13c

I tried the regular 'xapian' gem, but the version available in Debian unstable
is newer than the gem bindings, so that one outright refuses to compile.

Help!
