No such file to load -- gst

Rails
1

Hi

I was trying to install the rails application from
http://rubyforge.org/frs/?group_id=754&release_id=4492

As per the readme it says that i need to run

ruby scanner.rb d:\mp3

while running this I get the following error.

Does this mean that I need to install the gem “gst” ?

I tried " gem install gst " , but it failed.

Can you please let me know what this error is about ?

Thanks
Prasanna
