Unable to locate default.html theme file

[FlorianWolters]

First of all, I am using Windows 7 and Ruby 1.9.3.

I followed the installation instructions for Ruhoh and created a new blog:

ruhoh new myblog
cd myblog
rackup -p 9292

The last command raises a RuntimeError with the following stacktrace.

There is obviously a problem with the filepath (look at File not found: D:/myblog/D:/myblog/_templates/themes/twitter/layouts/default.html. I guess it is related to a Windows operating system withouth further investigation.
