The nagios daemon has nothing to do with the cgi's, except that it 
collects the data they display.

Not with these CGI's in particular, but with binaries in general.
First, you'll have to either compile the cgi's statically so they don't 
need any libraries or copy the relevant libraries to where the chrooted 
cgi's expects to find them. Compiling the cgi's statically is way 
preferrable, since you won't need to copy anything to the chroot jail 
that might give away what system you're using.

Secondly, you'll have to make sure the cgi's can read status-logs and 
such from within the chroot jail.

If you get the first step running but not the second, the cgi's will 
tell you that they can't read status data and so on, and throw an error.
