Would it be possible for me to log into your machine remotely to look at
it?  If that's not possible, would you be able to take the source files
from 5.2-CURRENT for src/tools/tools/aac, compile them on your RELENG_5_2
system, and send me the output from

aac_checkq 0
aac_checkq 1
aac_checkq 2
aac_checkq 3
