   LoadModule passenger_module /home/norx/.rbenv/versions/2.6.0/lib/ruby/gems/2.6.0/gems/passenger-6.0.4/buildout/apache2/mod_passenger.so
   <IfModule mod_passenger.c>

     PassengerDefaultRuby /home/norx/.rbenv/versions/2.6.0/bin/ruby
   </IfModule>

Validating installation...

 * Checking whether this Passenger install is in PATH... ✓
 * Checking whether there are no other Passenger installations... ✓
 * Checking whether Apache is installed... ✓
 * Checking whether the Passenger module is correctly configured in Apache... ✓

Everything looks good. :-)
