## gistfile1.txt
I'm having zero success vagrant provisioning social-service.  It fails to load various
gems.  When I ssh in and install manually, I get similar errors.  It seems I'm having
sporadic problems reaching rubygems.org. Googling for the error suggests a network
connectivity problem.

I've reset my wifi connection, restarted the vm, destroyed the vm, and tried it all again.
I feel like that it's not actually a network issue...but I'm running out of ideas and
wasting far too much time on this.

Any ideas?

...time passes

I've been repeatedly running bundle install, and it seems to get farther each time.  I
guess I'll keep hitting that until it gets everything.

*sigh

ps.  I copied various apporaches and errors here:

...but here's the punchline:


Gem::RemoteFetcher::UnknownHostError: no such name (https://rubygems.org/gems/diff-lcs-1.2.5.gem)
An error occurred while installing diff-lcs (1.2.5), and Bundler cannot continue.
Make sure that `gem install diff-lcs -v '1.2.5'` succeeds before bundling.
