Hi!

I’ve installed gd2 on my server (Debian), and I’ve installed the gd2  
gem, but i got this problem:

rake db:schema:dump --trace

(in /var/rails/feevy2)  
\*\* Invoke db:schema:dump (first\_time)  
\*\* Invoke environment (first\_time)  
\*\* Execute environment  
rake aborted!  
unknown symbol “gdImagePngEx”  
/usr/local/lib/ruby/gems/1.8/gems/gd2-1.1.1/lib/gd2.rb:150:in `[]' /usr/local/lib/ruby/gems/1.8/gems/gd2-1.1.1/lib/gd2.rb:150 /usr/local/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support/inflector.rb:250:in`inject’  
/usr/local/lib/ruby/gems/1.8/gems/gd2-1.1.1/lib/gd2.rb:150:in `each’  
…

Any idea? Thanks!
