problem seen when useing rbenv and bundler and moving between apps running ruby -v 1.9.3-p484 and ruby -v 2.2.1 with these apps
note: my solution shown here is now working for the moment using gem pristine with both versions now working at the same time

last problem app seen after bellow app bundler install:
https://github.com/sacarlson/stellar_utility commit d3150c5581cd88f08bc57e74b50265eea38e3c44  runs with ruby -v 1.9.3-p484
error seen:
sacarlson@sacarlson-asrock ~/github/stellar/stellar_utility $ rr create_account_save.rb
/home/sacarlson/.rbenv/versions/1.9.3-p484/bin/ruby: symbol lookup error: /home/sacarlson/.bundle/gems/json-1.8.3/lib/json/ext/parser.so: undefined symbol: rb_str_new_static

method to fix:
bundle exec gem pristine json

note: rr = bundle exec ruby
so: rr create_account_save.rb; is equivalent to: bundle exec ruby create_account_save.rb ;

the supposed conflicting app:
https://github.com/stellar/horizon commit a55b846d6a18a80f83b10785eac088ee209dbee4  run with ruby -v 2.2.1
error seen after above app bundler install to fix json problem:
sacarlson@sacarlson-asrock ~/github/stellar/horizon $ bundle exec gem pristine --all
