"apt-get install ruby rubygems" fails

Looks like ruby is halfway through switching default from 1.8 to 1.9;
ruby is 1.9, but rubygems is 1.8.

This is in a freshly created lxc container.

$ apt-cache policy ruby rubygems
ruby:
Installed: (none)
Candidate: 1:1.9.3.4
Version table:
1:1.9.3.4 0
500 http://archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages
rubygems:
Installed: 1.8.24-1ubuntu2
Candidate: 1.8.24-1ubuntu2
Version table:
*** 1.8.24-1ubuntu2 0
500 http://archive.ubuntu.com/ubuntu/ trusty/universe amd64 Packages
100 /var/lib/dpkg/status

Caused me a few hiccups. Looking forward to this being resolved.
Hoping I just forgot to do 'apt-get upgrade' in the lxc container, or something.

If you are programming ruby and/or rails - use rbenv or rvm to manage everything about the ruby environment. DO NOT TRUST the OS versions.

This is an OS forum, this thread is about fixing OS versions.

So the issue is that rubygems is 1.8 only. As https://launchpad.net/ubuntu/trusty/....8.24-1ubuntu2 says,
"In Ruby 1.9.X, Rubygems is provided with the interpreter".

At the moment, rubygems1.8 is a transitional package that depends on the package rubygems.
Given that Trusty is moving to 1.9 by default, that should be flipped; the real package
should be rubygems1.8, and rubygems should become a transitional package that does nothing.

I think the following dependency lines would let my private app's source package build and work across the range ubuntu 10.04-14.04:

libopenssl-ruby | dash,
ruby (>= 1:1.9.3.4) | rubygems,
ruby-dev,

I'll post back here if that's not a good enough workaround.
