  You have two versions of OpenSSL installed on your system.  One that
you used to build FreeRADIUS, and another that your dynamic linker
finds at run-time.  The versions are incompatible.

  It's not an "out of date" issue.  It's that you have *two* OpenSSL
versions installed.

  Force the server to link at run time with the version you used to
build it, and it will work.
