Hmm. Most likely, xymon wasn't built with OpenSSL included. The quickest
way to tell is to look at your "xymonnet" test (a snapshot from when
4.3.21 was running). If the OpenSSL version isn't indicated in the first
few lines, that's definitely the problem.

Do you have build logs from when this was originally run? And can you
indicate your distro and openssl-devel version?
