Won't this leave a lot of cruft behind over time? I don't see the point in  
keeping ancient shared libraries around for years and not knowing with  
confidence what versions your ports are linked to. I'd rather just follow  
UPDATING and make sure everything is properly linked against the newest.

On that note, does portmaster at least provide a way to keep track of  
libraries it kept due to the usage of -w ?
