Is return_index.pl installed on the client? I can't tell if the 'ls -al' and the error from cf-agent are from the same host. Also, the modules dir is 700 so the agent must be run by root.

Yes, its on the same host, its a test box which itself is the policy server, and the agent is run as root.

Run this policy with 'cf-agent -vlf /path/to/this_file.cf' and post the results:
body common control
{
bundlesequence => { "main", };
}
bundle agent main
{
classes:
"ok" expression => usemodule( "return_index.pl", "x 3" );
commands:
"/bin/ls -l ${sys.workdir}/modules/return_index.pl";
"/bin/cat ${sys.workdir}/modules/return_index.pl";
reports:
ok::
"return_index_pl => ${return_index_pl.x}";
}

Do you have selinux enforcement on? What are the results of 'sestatus'? Can you run the module in the shell?

It was perl :( there was no perl interpreter installed on the system for some reason. Thanks for your help!
