  The check is correct.  You have two versions of OpenSSL installed.

  Maybe you’re building the RPM on a system with version 1.1.5f of OpenSSL, and installing it on a system which has only 1.0.3.

  The issue is that OpenSSL changes its internal data structures in minor releases.  We’ve previously had FreeRADIUS crash when people “upgrade” their OpenSSL… and the data structures are different.

  We want to blame OpenSSL for the problem, rather than having people complain that FreeRADIUS crashes.
