Huh. Well, I'm wondering why I have ruby installed, if nothing depends on 
it.

But this is weird.

# pkg info -a | grep ruby
ruby24-2.4.6_1,1               Object-oriented interpreted scripting 
language
ruby24-bdb-0.6.6_5             Ruby interface to Oracle Berkeley DB 
revision 2 or later

 pkg info -r ruby24-bdb*
ruby24-bdb-0.6.6_5:

So, it depends on itself but not ruby? Double weird.

Oh well, I'll keep ruby installed if for no other reason than I can.
