I'm trying to get cricket (cricket.sf.net) to work on FC6 with SELinux

The ino number in the AVC is /var/cricket/cricket.
The application is installed in /var/cricket (from the legacy install)
but if necessary I can move bits and pieces around to accomodate
SELinux standards. I relabeled the entire /var/cricket tree to
httpd_script_exec_t.
httpd_sys_script_exec_t is the context for a cgi script.
You should label it httpd_sys_content_t and I think it will work better.

Here is my relavent Apache config:

<VirtualHost *:80>
ServerAdmin root@localhost
DocumentRoot /var/cricket/public_html
ServerName server.host.name
ErrorLog /var/log/httpd/cricket/error_log
CustomLog /var/log/httpd/cricket/access_log common
</VirtualHost>
<Directory "/var/cricket/public_html">

Allow from all
</Directory>
Has anyone had success running cricket with SELinux?
Thanks.
