configure problem

Hi. I'm new to bro and my first attempt to build the app (v0.9) failed - I
couldn't get by configure.

This turns out to be due to some files missing from the distribution.
I've now put out a new version of CURRENT, 0.9a4a (not 0.9a5, since that's
already been used internally), so please refetch and see if you still have
a problem.
