   message: <<EOM
 If this application is built in "compatibility mode" on amd64 it means that
 you're either using a prebuilt binary package or that CPUTYPE variable wasn't
 set during build. Application will still continue to work but without assembly
 optimization which means REDUCED performance. It is HIGHLY recommended that
 you recompile this software and plugins with CPUTYPE variable defined.
