ERROR: While executing gem ... (RuntimeError)
Unknown command open_conference_ware,
Which seems like a reasonable error as "open_conference_ware" isn't a command I'd expect it to know...
Am I running the wrong version of ruby?
gem -v returns 1.8.23.2
ruby-v returns ruby 1.9.3p547 (2014-05-14) [x86 64-linux]
