-> METALOG, line 7234 is this:
-> 
-> ./usr/share/man/cat3/tdelete.0 type=file mode=0444
-> sha1=8ff525da4b648fe8fdc54bd612fd1e0275e8bbee

The makesetfiles target prepends the contents of ${etcdir}/mtree/NetBSD.dist
to the METALOG, IIRC, so look there (and if it doesn't have enough lines
then look at line 7234 - `wc -l ${etcdir}/mtree/NetBSD.dist` - 1 of the
METALOG instead.  I tripped over this a while back and I *think* it was
a matter of old junk in my destdir causing the build.sh to blow chunks.

(And I think ${etcdir} is the source-tree's etc, but you can double-check
 that by looking in the maketars script & Makefile in distrib/sets)
