how to setup nulldb

Hello everyone,

can you tell me how can I setup nulldb in a rails app so I’ll be able to have fast sepcs.

I read through the nulldb github page and went through the installation and setup steps but I’m getting

some errors. I searched a lot but I didn’t find any useful thing for solving the problem.

here’s a question about it which I posted in StackOverflow -> http://stackoverflow.com/questions/10868408/how-to-set-up-nulldb-in-rails-with-rspec

also I created a gist for the complete error message and also the related files which can be found here ->
https://gist.github.com/2869276

I really appreciate your help on this.

Thanks in advance for your help.

Best Regards
