If you do not use the mswin32 port but rather the MinGW port, try explicitly calling gem install -platform=ruby fast-stemmer. That way, if the maintainer has provided a pre-compiled version, you don't need to compile it yourself. Try forcing the platform by explicitly calling gem install -platform=mswin32 fast-stemmer or even gem install -platform=x86-mswin32-60 fast-stemmer. Visual C++ 10.0 (which is what you seem to be using) does not work. In particular, you must use Microsoft Visual C++ 6.0, because that's what the mswin32 port is compiled with, and later versions of Visual C++ are not guaranteed to be binary compatible. If you use the mswin32 port, you are more or less on your own. Where does that mswin32 come from? Are you using the DevKit with the mswin32 port of MRI? The DevKit is only for the current MinGW port of MRI and YARV, it does not work with the mswin32 port (which, BTW, has been obsolete for quite some time now).
