As another monk mentioned, most of the reasons people think they can't install from CPAN are in fact non-reasons.

But either way, the uniq function from List::MoreUtils is easy for you to implement yourself:

sub uniq (@) {
    my %seen = ();
    grep { not $seen{$_}++ } @_;
}

As it happens, I just copied and pasted that code from List/MoreUtils.pm. However, one reason to prefer List::MoreUtils over a home-made version, is that List::MoreUtils provides an XS version which (over large lists) may run a little faster.
