I'm trying to install this gem: https://github.com/jongilbraith/simple-private-messages with bundle install.
And I'm getting the following error message:
Updating git://github.com/professionalnerd/simple-private-messages.git Fetching source index for http://rubygems.org/ Could not find gem 'simple-private-messages (>= 0, runtime)' in git://github.com/professionalnerd/simple-private-messages.git (at master). Source does not contain any versions of 'simple-private-messages (>= 0, runtime)'
entry in Gemfile:
gem "simple-private-messages",:git =>"git://github.com/professionalnerd/simple-private-messages.git"
Any ideas?

As per @bjeanes answer, ideally the Git repository should have a .gemspec file for each gem the Git repository represents.
However, if the repository is only missing the .gemspec file and would otherwise be a valid Git gem source, you can specify a version number in your gem call to have Bundler generate a .gemspec for you:
gem 'simple-private-messages', '0.0.0', :git => 'git://github.com/jongilbraith/simple-private-messages.git'
The git repo needs to have a .gemspec file in it in order to be a valid gem.
