RHC has a number of dependencies that are occasional updated to a point where they drop support for older versions of ruby (Ruby 1.8 and Ruby 1.9 are deprecated).  This causes problems as many customers are using rhc on RHEL systems with older versions of Ruby.  Likewise, many other customers use rhc on their personal machines with newer versions of Ruby, and we need to support those as well.

The net-ssh, addressable, and json gems have recently released newer versions that are not compatible with our older versions of Ruby.  Net-ssh was particularly difficult, as not only does the latest version not support older versions of Ruby, but older versions of net-ssh don't support newer versions of Ruby.  Addressable has similar issues with versioning that would break newer versions.


In order to fix this, rhc will now install a specific version of net-ssh and addressable depending on which version of Ruby is used to build rhc.  Customers who want to use rhc on non-RHEL systems are encouraged to grab the source from github and build it themselves to grab the proper dependencies for their version of Ruby.
