Can I assume this is on Debian? I see the problem popping up on Ubuntu also.
I think this is a problem with the ssl lib, so it's OpenSSL's bug since it seems to not affect Windows.
Edit: Bla bla bla
I really have no clue. I'm surprised it compiles but all SSL_CONF_CTX_* are supplied by openssl (ssleay). Maybe it's not getting added to the exports list, if unix uses them, or added but not compiled in, or a couple other possibilities. In any case, it's the wonderful world of new versions. You know, newer is always better right?
