I found¹ that latest releases of Hoe, ParseTree, RubyInline and even RC2 of Merb depend on a updated version of Rake.

The problem is that version 0.8.3 is buggy on Windows from both user and developer point of view.

Until those patches are applied, you can install a patched version using RubyInstaller gem server (gems.rubyinstaller.org)

gem install rake --source http://gems.rubyinstaller.org

You should end with version 0.8.3.1 which will be enough for tools like DataMapper, Hoe and others work properly again.

Hope this helps.

Next: DataMapper working on Windows, wait for a bit.

¹ consider this a rant, but I do my part: I show you my code.
