Is there a way to build a gem in such a way so that dependencies can be
resolved at installation-time?
I want users to be able to “gem install ruby-debug-ide”, and have the
ruby-debug-ide gem install either ruby-debug-base or ruby-debug-base19,
depending on the version of Ruby that they’re running.
I’m thinking maybe extconf.rb could do this, but just wanted to see if
anyone had any ideas.
