You don't need to do that!

Just grab the latest dar source package (dar-2.x.x.tar.gz) at
https://sourceforge.net/projects/dar/files/dar (2.6.14 or 2.7.0 as you
prefer)

install the necessary debian packages as listed in paragraph 1.1
of http://dar.linux.free.fr/doc/from_sources.html
(just ignore libthreadar in a first time)

then as explain in paragraph 2 run:
./configure
make
make install-strip

Doing that will install dar directly in /usr/local out of debian package
management, though you can remove the installed dar/libdar (for upgrade
for example) by running:

make uninstall

This is a workaround solution waiting for Debian to update their
packaged version

yes, you need doing these steps *only* when buiding code from git, which
is not the case when using source code from a tarball.

I will clarify the documentation about that.

Yes, I know this is the drawback and the advantage of Debian's quality
and stability.
