To recap what we found for windows users:

After these steps:

c:\hoboapps>  git clone git://github.com/tablatom/hobocookbook.git
c:\hoboapps\hobocookbook> git submodule init
c:\hoboapps\hobocookbook> git submodule update
c:\hoboapps\hobocookbook> rake db:migrate

We still get an error when you try to run the app:

http://screencast.com/t/ih80fMJU0

Because it is looking for this file:

C:/HoboApps/hobocookbook/app/views/taglibs/themes/clean/clean.dryml

For you 'nix guys, the symbolic link that is in the files:

    \hobocookbook\app\users\taglibs\themes\clean

and
    \hobocookbook\public\hobothemes\clean

work

If you look what is in the app:

http://screencast.com/t/lihqoTGZS0

   C:\HoboApps\hobocookbook\app\views\taglibs\themes\clean   (a file
containing the symbolic link)

We also see one here:

http://screencast.com/t/G5Vjnd0N3m

   C:\HoboApps\hobocookbook\public\hobothemes\clean (a file
containing
the symbolic link)

So we need to erase each of these and regenerate Hobo rapid:

c:\hoboapps\hobocookbook> erase app\views\taglibs\themes\clean
c:\hoboapps\hobocookbook> erase public\hobothemes\clean
c:\hoboapps\hobocookbook> ruby script/generate hobo_rapid

Now the folders we aneed appear:

And the app works liked expected:

Voila!

Now for Tom to help us not to need these steps!
