This backports base_dir which replaces installation path Rubygems 1.8+

This backports the correct segment generation code from Rubygems 1.4+ by monkeypatching it into the method in Rubygems 1.3.6 and 1.3.7.

Because Bundler has a static view of what specs are available, we don’t refresh, so stub it out.
