Git not building

[Baho Utot]

Update to latest ports revision ( svnlite )

building deve/git has this error:

install -d -m 755 /usr/ports/devel/git/work/stage/usr/local/libexec/git-core
install -m 755 git-subtree 
/usr/ports/devel/git/work/stage/usr/local/libexec/git-core
asciidoc -b docbook -d manpage -f ../../Documentation/asciidoc.conf \
         -agit_version=2.9.2 git-subtree.txt
xmlto -m ../../Documentation/manpage-normal.xsl man git-subtree.xml
install -d -m 755 /usr/ports/devel/git/work/stage/usr/local/man/man1
install -m 644 git-subtree.1

install: git-subtree.1: No such file or directory
gmake[3]: *** [Makefile:58: install-man] Error 71
gmake[3]: Leaving directory 
'/usr/ports/devel/git/work/git-2.9.2/contrib/subtree'

git-subtree.1 is missing:

find . -name git-subtree.1  <- displays nothing ie file not found

This a flea?
