the easiest way to tell if you have a module installed is
$ perl -MModule::Name
if you have the module perl will load it and wait (ctrl-d to exit), and if
you don't it will choke.
requires in eval { } 's is good for code that will be distributed and needs
to do different things based on what's available, but for just testing it's
huge overkill.
