Hello again, Lucas. Thanks for reporting this bug. Sorry for the delay in response: unfortunately the hard disk in my mail server died on Thursday night and since then I've been scrambling to try to recover what data I could and get it back up again after disk replacement.
I had a quick look at the bug and the build log, and I think you pointed out the correct section of the log where the compile went awry. I should be able to look more deeply at this on Monday. Meanwhile I'll try to inform upstream about the problem so that they're aware. Thanks. -- Chris
