I'm updating my SqlStatement gem http://sqlstatement.rubyforge.org/ to be
compatible with Ruby 1.9, and owing to totally different ways of doing s-
expressions in Ruby 1.8 (which required RubyNode) and 1.9 (which can trap
the not and != operators as methods, so I can use the interpreter itself
to generate everything I need in an s-expression), the Ruby 1.9 version
no longer requires a dependency on RubyNode. In fact, RubyNode doesn't
exist for 1.9 AFAICT.
Is there a way to do one of the following in RubyGems?
* create a Ruby 1.8 flavor of the gem and another Ruby 1.9 flavor.
Preferably, I'd like the gems to have the same name and live side-by
side on RubyForge.
or
* Have both versions of the dependencies exist in a single gem,
but only enforce the RubyNode dependency when the gem is installed on
Ruby 1.8.

Take a look at how the mongrel gem is doing it. It uses a bunch of conditionals to distinguish actions to perform for jruby and mri. adding in Ruby 1.9 support is (fairly) easy.
I forked mongrel the other day so I could take out the fasterthread dependency (not needed for 1.8.6+); might be useful: GitHub - dvdplm/mongrel: Mongrel on git
(and I'm sure it can be done more elegantly!)

AFAICT from the metadata of the generated gems, this doesn't do what I
want. It generates different gems on different versions of ruby, but
there's no indication that these gems are different in the end. By the
way, I think you have a bug: if you generate the gem on Ruby 1.8.6, it
will be installable on Ruby 1.8.4 but won't include the fastthread
dependency.
