The problem with gemspecs: If you define something in "extensions", rubygems will try to run the extconf for that extension. To avoid that, extensions must be cleared (extensions.clear()) like we are doing with mongrel gems: http://rubyforge.org/viewvc/trunk/Rakefile?revision=441&root=mongrel&view=markup Guess a notice / faq should be used to warn the user about this: Q. When installing gem 'name', two versions are shown, which one should I choose? A. If you're a Windows user, mostly you don't have a compiler/build environment like Visual C to compile and build the extensions bundled with the gem. In that case, please choose the pre-built version (marked as platform specific gem: mswin32). -- Luis Lavena Multimedia systems - Leaders are made, they are not born. They are made by hard effort, which is the price which all of us must pay to achieve any goal that is worthwhile.
