       The perl bindings are located in various subdirectories of:
         #{opt_lib}/perl5
 
-      If you wish to use the Ruby bindings you may need to add:
-        #{HOMEBREW_PREFIX}/lib/ruby
-      to your RUBYLIB.
-
       You may need to link the Java bindings into the Java Extensions folder:
         sudo mkdir -p /Library/Java/Extensions
         sudo ln -s #{HOMEBREW_PREFIX}/lib/libsvnjavahl-1.dylib /Library/Java/Extensions/libsvnjavahl-1.dylib
