get 302 error while trying to deploy a ror site.

Hi All,

I am trying to install a rails app ( openmind ) and i am getting 500
internal server on the webpage :
Additionally, a 500 Internal Server Error error was encountered while
trying to use an ErrorDocument to handle the request.

While if i run dispatch.fcgi This is the result

]# ./dispatch.fcgi

I guess there is some problem with .htaccess

------------------------------.htaccess

General Apache options
AddHandler fcgid-script .fcgi
AddHandler cgi-script .cgi
#Options +FollowSymLinks +ExecCGI

# If you don't want Rails to look in certain directories,
# use the following rewrite rules so that Apache won't rewrite certain
requests
