The important words are:
"This library is free software; you can redistribute it and/or modify it
under the same terms as Perl itself."
which makes it simply LICENSE="|| ( Artistic GPL-1+ )", and of course,
no mirror restriction is needed.

The rest is simply an additional warranty disclaimer. I wouldn't even
see it as part of the license, because it is about usage of the
software, not about its distribution.

As always: IANAL, TINLA.
