It's an x86 machine. Nagios was configured with:
--prefix=/opt/nagios --with-cgiurl=/cgi-bin/nagios --with-htmurl=/nagios
--with-nagios-user=nagios --with-nagios-group=nagios
--with-gd-lib=/usr/local/lib --with-gd-inc=/usr/local/include
--disable-statusmap --disable-statuswrl

Thanks for the advice. We are currently using 2 Linux distributions:
RHEL and Fedora, but we are looking into CentOS right now.
