Recent (as of 3 Aug 2011) versions of LWP in Macports seem to have

broken SSL certificate verification.  The IU CA is in my Mac system
keychain (and has been there for quite a long time), but after a
recent ports update, LWP fails the SSL certificate verification.
Fine.  So we'll just turn it off, per
http://search.cpan.org/~gaas/libwww-perl-6.02/lib/LWP/UserAgent.pm.
