The warning message could occur e.g. when using the active check "check_bi_aggr"or other components on older distros that ship with an old OpenSSL version thatis not supported anymore by the OpenSSL project.
The message is:
"You are linking against OpenSSL 0.9.8, which is no longer
RuntimeError: You are linking against OpenSSL 0.9.8, which is no longersupport by the OpenSSL project. You need to upgrade to a newer versionof OpenSSL."
Basically this is only a warning message, but prevents some components form workingproperly because scripts are producing unexpected output.
