You may have better luck using "git update-index" instead of
git-update-cache. If that doesn't work, try finding out which
version of git the importer script was written against and try
using that version of git for the import.

If you run into problems while using a newer git on the
imported repository that'll be a different discussion.

It should still do this, afaik, although it's probably better
to just use GIT_DIR nowadays.
