[Dovecot] Is the trunk version of Pigeonhole still broken or am I missing something?

Things broke a couple of months back and I thought I had caught the repository at a bad time, but trying again today, after having seen that people had been working on it recently, bore the same result.

../../../../libtool: line 2072: cmd-vacation.c: command not found

I'm simply syncing with the repository and using autogen, configure and make. Are there any other steps required?
