I have the same dependency problems pretty often and they really put a spanner in the works. `activate': can't activate RubyInline (= 3.7.0, runtime) for ["tomdoc-0.1.0"], already activated RubyInline-3.8.6 for ["ParseTree-3.0.5", "tomdoc-0.1.0"] (Gem::LoadError) What do people do in these situations? Is it possible to activate specific gem version for specific gem(s) , or does that make no sense? -- Posted via http://www.ruby-forum.com/.
