I ran into the same issue when I had a
.git directory in the
/ directory. Try the patch in my PR:
http://www.freebsd.org/cgi/query-pr.cgi?pr=174422
The problem is that the
newvers.sh script is broken. It somehow works for SVN but the GIT revision detection breaks because the
newvers.sh is sourced instead of executed, resulting in
$0 being set to
/bin/sh instead of the path to
newvers.sh and the GIT revision detection ends up finding the
./git directory instead of the intended
/usr/src/.git.
