Turns out this wasn't quite as painful as I thought it would be, so I've 
added the feature to svn version r210440. On my system, without a full 
ports tree, it takes between 3.5 and 4.5 minutes to build the list.

This is certainly an interesting idea, however it has a lot of potential 
problems. Best case scenario on a default system with ports tree updated 
just before locate.db is created, on average the information would be 
3.5 days out of date.

There is also another problem, not all of the ports' distinfo files are 
named "distinfo." Most of them are, but not all.

It's not 100% clear to me what you're timing here, but it took 2.5 
minutes to do it.

Currently --clean-distfiles doesn't attempt to validate that the file 
matches the specs in the distinfo file, and I don't see a compelling 
reason to add that feature. It would be very difficult (nearly 
impossible) to accidentally save an invalid file, and totally impossible 
to use one to build a port.

Sorry I'm so dense, but I'm still not following exactly what part of the 
process you're referring to here, but this time it took over 8 minutes. 
Given that the method I'm using to generate a 100% up to date version of 
the list that's guaranteed to get all the distfiles takes less time, I 
do not think I will be adding the feature you are suggesting, but I do 
appreciate the suggestion. :)
