nginx, spawn-fcgi and php on freebsd - adding '/' incorrectly

[khine]

hello, i have nginx setup, but i have a weird problem and i am unsure
whether it is to do with the application or something i messed up on the
nginx.conf file:

[code]
    server {
        listen 87.98.133.231:80;
        server_name dev.editionsdelga.fr;

        location / {
                root /www/dev.editionsdelga.fr/1.3.6;
                index index.html index.htm index.php;
                #see

                rewrite
^/([a-z0-9]+)\-([a-z0-9]+)(\-[_a-zA-Z0-9-]*)/([_a-zA-Z0-9-]*)\.jpg$

                rewrite ^/([0-9]+)\-([0-9]+)/([_a-zA-Z0-9-]*)\.jpg$
/img/p/$1-$2.jpg last; 
                rewrite

last;
                rewrite

                rewrite

                rewrite

                rewrite ^/([0-9]+)\-([a-zA-Z0-9-]*)(.*)$

                rewrite ^/content/([0-9]+)\-([a-zA-Z0-9-]*)(.*)$

                rewrite ^/([0-9]+)__([a-zA-Z0-9-]*)(.*)$

                rewrite ^/([0-9]+)_([a-zA-Z0-9-]*)(.*)$

                rewrite "^/lang-([a-z]{2})/(.*)$ /$2?isolang=$1" last; 


        }
        # pass the PHP scripts to FastCGI server listening on
127.0.0.1:9000
        #
        location ~ \.php$ {
                fastcgi_pass   127.0.0.1:9000;
                fastcgi_index  index.php;
                fastcgi_connect_timeout 60;
                fastcgi_send_timeout 180;
                fastcgi_read_timeout 180;
                fastcgi_buffer_size 128k;
                fastcgi_buffers 4 256k;
                fastcgi_busy_buffers_size 256k;
                fastcgi_temp_file_write_size 256k;
                fastcgi_intercept_errors on;

                fastcgi_param  SCRIPT_FILENAME 
/www/dev.editionsdelga.fr/1.3.6$fastcgi_script_name;
                fastcgi_param SERVER_NAME $http_host;
                fastcgi_ignore_client_abort on;
                fastcgi_param  QUERY_STRING     $query_string;
                fastcgi_param  REQUEST_METHOD   $request_method;
                fastcgi_param  CONTENT_TYPE     $content_type;
                fastcgi_param  CONTENT_LENGTH   $content_length;
                }
        } # end server for dev.editionsdelga.fr

[/code]

when you view the site, all links are missing the last '/' so instead of
getting http://dev.editionsdelga.fr/manufacturer.php
you get http://dev.editionsdelga.frmanufacturer.php/

Any advice much appreciated.
