Uhhhhh...... I think we should assume a port does not violate the  
mtree. And... that doesn't seem to address the problem I'm trying to  
solve. I maintain a couple dozen ports, and I would like to reinstall  
each of them and ensure there are no mtree violations. I'm just  
looking for an easy way to see the mtree errors, if there are any.  
I'll try using debug mode with grep, as Anders suggested.
