There you have it. You can also look at the output of configure
(embedded Perl is a configure option).

You can skip the embedded Perl execution by calling the Perl binary
within Nagios. I.e. in your command definition:

command_line    /usr/bin/perl $USER1$/check_stuff.pl <some_args>

While this is an option it is always better to fix your Perl script as
embedded Perl execution is much faster (the plugin is compiled only once
and there's no forking necessary).

This is a good guideline fro writing ePN plugins:

You can also use Nagios::Plugins which can make your life much easier...
