I'm trying to set up Substruct (shopping cart engine) on Dreamhost.
I failed several times and tracked down to the problem area.
I can reproduce the problem with these steps:
1. install rails
2. change public/.htaccess for fcgi
3. change public/dispatch.fcgi for RailsFCGIHandler
At this step, I can execute public/dispatch.fcgi without error.
4. svn co http://dev.rubyonrails.org/svn/rails/tags/rel_1-1-6 vendor/
