SELinux and Nagios (Fedora 9 + Nagios)

Hello,
I've setup (via default yum repos) Nagios (nagios-2.11-3.fc9.i386 and all the needed plugs).
I'm getting the following messages when using SELinux in Target/Enabled mode.
My knowledge is very limited with SELinux and I'm trying to learn the proper way to troubleshoot/resolve issues on my own, and hopefully I can use this as my firts learning curve with it.
Thanks for any suggestions.
Summary:
SELinux is preventing ping (ping_t) "read" to
/var/spool/nagios/cmd/nagios.cmd
(nagios_spool_t).
Detailed Description:
SELinux denied access requested by ping. It is not expected that this access
is
required by ping and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.
Allowing Access:
You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can
disable
SELinux protection altogether. Disabling SELinux protection is not
recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.
