At this time 1.3.1 appears to exist only as a patch to the _sources_. 
Meaning that it's only useful if you're commited to first downloading all
the sources, and then rebuilding userland. It's main purpose seems to be
to save a lot of time if you're setting up a new machine to run -current,
as there are extensive changes in the libs and tools since 1.3.
