[DRE-maint] Bug#1029523: ruby-net-http-persistent want Ruby (~> 2.1)

[Pirate Praveen]

Package: ruby-net-http-persistent
Severity: grave
Justification: unable to install gitlab or use with bundler

Just add this to Gemfile.
gem "telesign"

and run,
bundle install --local
Don't run Bundler as root. Bundler can ask for sudo if it is needed, 
and installing your bundle as root will
break this application for all non-root users on this machine.
[DEPRECATED] This Gemfile does not include an explicit global source. 
Not using an explicit global source may result in a different lockfile 
being generated depending on the gems you have installed locally before 
bundler is run. Instead, define a global source in your Gemfile like 
this: source "https://rubygems.org".
Resolving dependencies...
Bundler found conflicting requirements for the Ruby version:
  In Gemfile:
    Ruby

    telesign was resolved to 2.2.3, which depends on
      net-http-persistent (~> 3.0, >= 3.0.0) was resolved to 3.1.0, 
which depends on
        Ruby (~> 2.1)


This comes from the gemspec
