2.0.10 for missing Ruby 2.2.x compatibility

[nathan-nhm]

Why Ruby 2.2.x ? because that's the last version Rails 3.2.x supports.

This is a long upgrade path.

How about using old locale gem?

[nathan-nhm]

Rails 3.2.x - including activesupport - supports up to Rails 2.2.x
activesupport 3.2.22.5 needs lib/gettext/runtime/locale_path.rb , which gettext > 2.3.9 does not provide
gettext 2.3.9 needs locale/util/memoizable , which locale 2.1.0 removes
locale 2.0.9 requires 'dl/import' which is not available past Ruby 2.1.x

locale 2.0.5 does not have the requirement of 'dl/import' - as there is an easy replacement, I would prefer to depend on the newer code.

I could make Ruby 2.1.x work without a new version of Locale - Or I could update the version of rails, which I eventually hope to. This might be months away.

That said, I would be happy to spend more time testing this pull request before further consideration. (or, re-submit to an appropriate branch.)

It's OK that we use Fiddle instead of DL.
But we don't release a new version based on 2.0.9. Because both of Ruby 2.2 and Rails 3.2 reached EOL.

I suggest that you use Ruby 2.1 until you update your Rails.
