The interesting thing is that this didn't happen in 4.99.72 (from ~ mid-
August 2008); I was able to configure and build a couple of the Asterisk
1.6 betas succesfully, and had no trouble with 1.6.0.1.

My round-toit supply has been short but maybe I'll upgrade one of my
4.99.72 systems to 5.0_BETA and see what differs there.
