N00b question

Hi!

I'm new in ruby/rails programming and i have a small problem.

I have installed InstantRails 1.0 (for Ruby/Rails/Mysql/Apache envs) and 
I'm trying to make a small app working. I'm using auth_generator for 
making a login page/users admin pages... and I have a problem when 
trying to CHANGE the avatar for the user.

I have the following error:


  MissingSourceFile in Account#info

no such file to load -- GD

|This error occured while loading the following files:

    Request

"picture"=>#<StringIO:0x395e3f8>, "password"=>"", 
"newemail"=>"aaa / bbb.com", "passwordbis"=>""}}



it is related with GD module (I guess).. so, i've downloaded ruby-gd 
from http://raa.ruby-lang.org/cache/ruby-gd/ruby-GD-0.7.4-1.tar.gz and 
unzipped it into [instantRails_path]/ruby folder. And I still get that 
error.

Do I need to configure/download/install something mode?

TIA

Daniel.
