Loading a single file

Hi!

How can I load a single file within a configuration? I tried the following:

spec project: 'Additional parsers' with: [
       spec
               className: 'PetitXml';
               file: 'PetitXml';
               repository: 'http://www.squeaksource.com/PetitParser'.

       spec
               className: 'PetitSmalltalk';
               file: 'PetitSmalltalk';
               repository: 'http://www.squeaksource.com/PetitParser'. ].
      ].

But I got an error (no version found).

Cheers,
Alexandre
