BIND's Queryperf on OS X
I've found the queryperf tool from ISC's BIND contrib package to be a pretty useful tool for testing the custom DNS servers I've been developing for Enemieslist over the past few months (with help from Matt Sergeant and Brent Verner); the problem is, it doesn't compile out of the tarball on OS X Tiger, because of a problem with BIND 8 compatibility. The fix is to define BIND_8_COMPAT in the Makefile generated by configure. Just slap
-DBIND_8_COMPAT
on the end of the DEFS line, and voila.
