I'd be Lion if I said it was going well

What is "brtool" and why is it (or a lack of it) killing my Lion upgrade?

Apple won't help me upgrade from Snow Leopard Server to Lion Server beyond "try installing to another partition" (unless I pay for enterprise support at $695 a pop), so I thought I'd see if you folks have any ideas.
Basically, I download and run the Lion installer, and it gets to the point at which it will restart...but the restart fails, with a crash related to "brtool". Google has failed me on what "brtool" might actually be, on a Mac or just generally.
Here's the crash report header:

Dyld Error Message:

Any ideas? Oh, and a manual restart of the machine does NOT boot into Lion; it still boots in Snow Leopard Server.
