HEAD not building due to missing class

[Warwick Burrows]

Guys, 
 
The HEAD isn't building for me because the following class is missing:
 
    org.apache.commons.contract.Information
 
There's an apache commons contract JAR in the project lib dir
(commons-contract-0.2.jar) but it doesn't have a class called "Information"
defined in it. I checked the commons contract Java doc on the web page and
they don't mention an Information class either. Any idea where it is
supposed to come from?
 
Thanks,
Warwick
