Comment (by ryandesign):

 Granted, this uses a slightly older data file. The one in the release
 download is from 9/14/2017, while the one the port is currently
 downloading is from 10/28/2017. If it's desired to update to newer data
 files than what's in the release download, then I can provide an alternate
 patch.
