... and OpenSSL I assume.

What platform? I've had https problems on Solaris 2.7. From what I've found so far I can't just use the latest triplet of LWP::UserAgent/Crypt::SSLeay/OpenSSL. I've managed to get a set of these three that work okay together, but each one is several versions off the latest. I got various errors when they weren't happy.

I tried this a few months ago though. Since then, a friend of mine says he has gotten all three latest versions to work together. And from posts I read on the libwww mailing list this was only a problem on Solaris for some reason.
