If you wanted check from within your script/program you could try something similar to the following (which is from Chapter 12 of the Perl Cookbook):

BEGIN {
    unless (eval "use $mod") {
        warn "couldn't load $mod: $@";
    }
}

I find this useful for version checking modules and throwing out meaningful errors to users, if they're lacking a particular module.
