I downloaded http://cdn.netbsd.org/pub/pkgsrc/current/pkgsrc.tar.bz2
from the link on the web page http://pkgsrc.org under "get pkgsrc". I
did a cvs update just now, and bootstrap errored out with the same
error. (I ran cleanup first)
pkgutil(1) seems to give a version of 188.8.131.52.1.1588476445 for the
Command Line Tools. Xcode is not installed.
