Description of problem:

Trying to start a fresh jekyll project, the user is asked to run `bundle install`.  But, it does not use the installed rubygem-rb-inotify and instead downloads it from the internet.  This does not make sense, the only reason `bundle install` was required was to install the minima theme.

Version-Release number of selected component (if applicable):

rubygem-bundler-1.12.5-1.fc25.noarch
rubygem-listen-3.1.5-1.fc25.noarch
rubygem-rb-inotify-0.9.7-1.fc25.noarch

How reproducible: always


Steps to Reproduce:
1. dnf install rubygem-jekyll
2. jekyll new testblog
3. cd testblog
4. bundle exec jekyll serve
5. run `bundle install` if suggested

Actual results:

$ bundle exec jekyll serve
Could not find gem 'minima' in any of the gem sources listed in your Gemfile or available on this machine.
Run `bundle install` to install missing gems.

Bundle complete! 2 Gemfile dependencies, 17 gems now installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.

Expected results:

bundler should not have installed rb-notify, when the jekyll RPM had already pulled in rubygem-rb-inotify-0.9.7-1.fc25.noarch.  See below.

Either this is a bug in bundler, or there is some issue with the rubygem packaging which I can't find.


Additional info:

Look in the Gemfile (below), and you see that

1. the only gem with a dependency on rb-inotify is `listen`.
2. `listen` requires `rb-inotify (~> 0.9, >= 0.9.7)`

$ gem list | grep rb-inotify
rb-inotify (0.9.10, 0.9.7)


$ cat Gemfile.lock
