[root@sun ~]# <input>cd /usr/ports/net-mgmt/nagios</input>
[root@sun /usr/ports/net-mgmt/nagios]# <input>make</input>

*** Compile finished ***

If the main program and CGIs compiled without any errors, you
can continue with installing Nagios as follows (type 'make'
without any arguments for a list of all possible options):

  make install
     - This installs the main program, CGIs, and HTML files

  make install-init
     - This installs the init script in /usr/local/etc/rc.d

  make install-commandmode
     - This installs and configures permissions on the
       directory for holding the external command file

  make install-config
     - This installs *SAMPLE* config files in /usr/local/etc/nagios
       You'll have to modify these sample files before you can
       use Nagios.  Read the HTML documentation for more info
       on doing this.  Pay particular attention to the docs on
       object configuration files, as they determine what/how
       things get monitored!

  make install-webconf
     - This installs the Apache config file for the Nagios
       web interface
