Sorry, I should've been clearer. Currently send-email fails for me with this error: SSLeay.c: loadable library and perl binaries are mismatched (got handshake key 0xdb80080, needed 0xde00080) I thought the undefined symbol stuff in the .so could have been part of the problem, but I guess not. None of the fixes that worked for Liam worked for me either, so I'm not quite sure where the issue is. The closest I've found to a meaningful suggestion for the error is that Perl is relying on a library built against a different version of Perl, but I have no idea what library that might be.
