The first thing I did was look for a bug tracker, but I couldn't find 
one.  There are no trackers on the SF page and I see no mention of a bug 
tracking system on the home page.  I found an email from Ethan in the 
dev list (Jan '04) saying to post bugs directly to nagios-devel.  Is 
that still the best way?  I'll post it to the list anyways.
