Because it isn't passing distcheck. Here is the error that I'm getting. It's correct that there is no libtool in that directory... I've compared pre2 and pre3 pretty extensively and can't find any differences related to libtool. Hmmm... I'll keep looking, but anyone has ideas I'd love to hear them.
