1.6.0 no longer is a pure ruby install about regexp-examples

[tom-lord]

As commented here:

regexp_property_values ... includes C-extensions. The extensions are optional, and the fallback code has successfully been used in some non-C-Ruby environments, but I wouldn't vouch for them to work in every exotic setup

I didn't test this library on non-native builds, so haven't experienced an error. The mentioned dependency claims to have optional extensions, and I see the key code to support it is here. Maybe the issue would be better raised in that project, if you have an installation error?

Barring that, you may have to stick with v1.5.x of this gem.

The code is great; the problem is that bundler and gem do not know that this is a conditional dependency. So you cannot gem install or bundle install 1.6.0 without a compiler. The question is how to create such a conditional dependency.
