Thanks for pointing that out.  I should have explained here.
This user posted the same request to at least two
other mailing lists and there was a fine response on
at least one of those others.

Here's some explanation and an outline:

coreutils-6.7 was released on 2006-12-08, which was before we had a
gnulib git submodule.  Actually, that was back when bootstrap would
pull the gnulib sources via cvs.  coreutils itself had switched to
git only two months before.

Hence, without a submodule, and with no other record of which gnulib
commit was used, you'll have to resort to dates to find approximately
which gnulib was used.  Or compare with the release tarball.

Since cvs access to gnulib may not do what you want, I suggest
using a ../gnulib directory.  You'd git-reset it to a commit from
the date corresponding to 6.7 and then reference ../gnulib via the
GNULIB_SRCDIR=../gnulib envvar setting that bootstrap uses.

From there on, you'll just have to debug problems as you find them.
There is no general recipe.
