I\'m having problems getting thin working on my Windows 7 machine (I\'ve already installed eventmachine v0.8.1):

gem install thin --i
Apparently, there aren't any pre-built binaries.
You will need a C compiler installed. If you installed Ruby via the RubyInstaller, that is going to be really easy, if you used the One-Click Installer, it's goint to be a PITA.
See also: problems installing thin on Windows, which contains an answer by the RubyInstaller and One-Click Installer maintainer.
