Can't Build FreeBSD 10.2

[Tim Gustafson]

I have a FreeBSD 10.0 box onto which I've downloaded a fresh copy of
10.2 into /usr/src via subversion, like this:

rm -R /usr/src /usr/obj
svn checkout http://svn.freebsd.org/base/releng/10.2 /usr/src

I'm currently on revision 292152.  Then I did:

cd /usr/src
make buildworld

And I'm getting the following error:

I tried building the RELENG-10.0 and RELENG-10.1 and am getting the
same behavior on both.  What am I doing wrong here?  Is something
hosed on my 10.0 system such that there's some library missing or
something?  It seems that freebsd-update is also not working.  When I
run:

freebsd-update upgrade -r 10.2

it spends a bunch of time downloading stuff, but then it spits out the
following line about a hundred times:

/usr/sbin/freebsd-update: cannot open files/.gz: No such file or directory

and then it starts prompting me to delete a whole bunch of stuff that
I know it shouldn't be, like:

The following file will be removed, as it no longer exists in
FreeBSD 10.2-RELEASE: /boot/device.hints
Does this look reasonable (y/n)?

If I answer "no" to that question, freebsd-update immediately exits.

Is my system totally broken or is there some way to save it?
