What an overzealous configuration. I hope you're talking about 
servicedependencies, otherwise you've badly misunderstood the concept of 
parents and unreachable hosts.

That's what --enable-DEBUG4 is there for. Use it and run Nagios in 
debug-mode when debugging (obviously).

Otherwise you could always hack up some tool to calculate dependencies 
for you. I would suggest writing it in C and utilizing code from Nagios 
(you'll be wanting common/objects.c and xdata/*.c and all the header 
files they use).
