You didn't have the proper gd libraries and headers installed at the
time of compiling. I'm not sure where you can find those from HP-UX, but
for RedHat you *should* get everything needed by the simple expedient of
yum install gd-devel

The error message tells you exactly what's going wrong.
"Permission denied: exec of '/usr/local/nagios/sbin/status.cgi' failed"
You need to make sure the user apache is running as can execute the
status.cgi binary. The easiest way to do that is to do like this,
assuming the apache pseudo-user is called "httpd"
su httpd
cd /usr/local
cd nagios
cd sbin
./status.cgi
The reason for doing it in steps is that you likely have not only faulty
permissions on the status.cgi program, but somewhere along the path as
well. Doing it like this will let you see at which points you need to
modify the permissions in order for httpd to be able to execute the
program, so just chmod your way there.
