On this branch, I have 2 patches.
http://gnuradio.org/cgit/jblum.git/commit/?h=freebsd_tweaks&id=ca3868256079060993ebb643e34b39c558052ce0

1) make qwt find script better. Its fixes the need to manually specify
-DQWT_INCLUDE_DIRS

2) Use CLOCK_GETTIME and not MACH_ABSOLUTE_TIME. Question: Did gr-qtgui

mach kernel headers?
