Dear Monks,

is there a way to specify dependencies on external programs or libraries in perl modules? Specifically if I use ExtUtils::MakeMaker. I know how to specify dependencies on other perl modules, so that's not what I need.

Let's say I wrote a perl module that uses calls the 'wget' binary via IPC::Run. Of course this will never work if we don't have wget in our $PATH, but I would be pleased if there was a way to tell the CPAN Testers that they should install wget before attempting to test this module.

Of course I could just test if wget is there and skip all tests if not but that's also suboptimal as I wouldn't get much info from the automated testing. And yes, I know there are perl modules that have the same/simillar functionality as wget! That is not my question, wget just serves as an example here.
