Unfortunately, an unexpected error occurred, and Bundler cannot continue.

First, try this link to see if there are any existing issue reports for this error:
https://github.com/rubygems/rubygems/search?q=Illformed+requirement+%5B%22

Rather than go down the rabbit hole I realized I no longer need to build this from, source. I'm just going to install it the regular way now.
