Here's a portage of the stat command line utility. Grab it from: http://cdf.toronto.edu/~agenkin/stat.tar.gz
BTW, I think that this one should be a part of the base install. It's a fairly standard utility on Unix systems.
I just added this to CVS, so it'll be showing up on anoncvs/rsync soon. Arcady, please take a good look that the ebuild and note *all* the changes that I made. Since you're probably going to end up with access to CVS soon, I want to make sure that you are up to speed on the fundamentals. Thanks! :) I'm leaving this one out of the base install until it's requested by someone (else?) :)
