 yes,

 Try this :

pigeon% cat b.rb
#!/usr/bin/ruby
require 'bdb'
module BDB
   class A < Btree
      def bdb_bt_compare(a, b)
         a.downcase <=> b.downcase
      end
   end
end

db = BDB::A.open "basic", nil, "w"
db["Fred Jones"] = "abc"
p db["fred jones"]
p db.keys
pigeon% 

pigeon% b.rb
"abc"
["Fred Jones"]
pigeon%
