Well, the OP said he wanted to start with a specific package, so it sounds like he knows that will be the root of the tree. In addition, I don't expect it's proper form for a dependency tree to be cyclic... that would be impossible to work with, realistically speaking. -- Jeff "japhy" Pinyan [EMAIL PROTECTED] http://www.pobox.com/~japhy/ RPI Acacia brother #734 http://www.perlmonks.org/ http://www.cpan.org/ CPAN ID: PINYAN [Need a programmer?
