> Can you try running bootstrap again on your machine?

Unless something very strange is going on, there also seems to be a
bug in the bootstrap script:

bootstrap/bootstrap contains:

run_cmd "$install_sh -c -o $user -g $group -m 755
$wrkdir/install-sh/install-sh $prefix/bin/install-sh"

(line 702 - note that this only occurs on OS where "need_bsd_install"
is set, and so may not have been picked up)

Now "$wrkdir/install-sh" exists, and is the install-sh script.
However, "$wrkdir/install-sh/install-sh" doesn't, and so the script
fails.
