Problem running local Gem server.

00-Local Gem server question.md

I have two systems on my local network, alpha.local and bravo.local. alpha is a Mac (OS X 10.8.5); bravo is a Linux box (Fedora 20).

1. On bravo, I start gem server -V and get the message Server started at http://0.0.0.0:8808;
2. On alpha, I run gem list --source http://bravo.local:8808, which produces a full list of gems installed on bravo;
3. On alpha, I then run bundle install --gemfile Gemfile_local --jobs 3 --path vendor; it fails with the output

Updating git://github.com/bbatsov/rubocop.git
Fetching source index from http://bravo.local:8808/
Retrying source fetch due to error (2/3): Bundler::HTTPError Could not fetch specs from http://bravo.local:8808/
Retrying source fetch due to error (3/3): Bundler::HTTPError Could not fetch specs from http://bravo.local:8808/
Could not fetch specs from http://bravo.local:8808/

What am I doing wrong? My Gemfile_local is below; rather obviously, it's copied from my project's regular Gemfile, with only the source replaced.
