[help-GIFT] how to start gift

[ahai]

    Hello!This is my first time to use gift.I have done as following steps which is written in READE.Debian:
         * mkdir gift-data
         * cd gift-data
         * cp /usr/share/libmrml1/gift-config.mrml .
         * export GIFT_HOME=`pwd`
         * gift-add-collection.pl /path/to/your/huge/collection/of/images
         * gift & # and hope it runs
         * gunzip < /usr/share/doc/gnuift/examples/Client.php.gz > \
             /path/to/a/webserver/accessible/directory/Client.php
         * access the url with a browser and enter the host where gift is
           running
    When I finished it.I got a webpage .

    But when I clicked the button.It returned nothing.What's wrong with it?How can I get it start?
    I am using "ubuntu 12.04".Thank you! :-)
