import - try to use Module in Perl and print message if module not available

I wanted to be able to do this in Perl (the code below is Python lol)

try:
  import Module
except:
  print "You need module Module to run this program."

Does anyone have any idea how to?

TIMTOWTDI:

eval "use Module; 1" or die "you need Module to run this program".

or

require Module or die "you need Module to run this program";
Module->import;

or

use Module::Load;

eval { load Module; 1 } or die "you need Module to run this program";

You can find Module::Load on CPAN.
