Is freetype-2.4.12 as included in SDL_TTF broken?

Is freetype-2.4.12 as included in SDL_TTF’s “external” folder broken? I checked that freetype’s docs/INSTALL.UNIX, and it says to just run ./autogen.sh and ./configure, but that seems to be plain broken:

[freetype-2.4.12]$ ./autogen.sh 
generating `configure.ac'
running `aclocal -I . --force'
running `libtoolize --force --copy --install'
libtoolize: putting auxiliary files in '.'.
libtoolize: copying file './config.guess'
libtoolize: copying file './config.sub'
libtoolize: copying file './install-sh'
libtoolize: copying file './ltmain.sh'
libtoolize: Consider adding 'AC_CONFIG_MACRO_DIRS([m4])' to configure.ac,
libtoolize: and rerunning libtoolize and aclocal.
libtoolize: Consider adding '-I m4' to ACLOCAL_AMFLAGS in Makefile.am.
running `autoconf --force'
[freetype-2.4.12]$ ./configure
make: *** No rule to make target 'setup'.  Stop.
[freetype-2.4.12]$ 

So is this just a broken tarball? (But why would it be included in SDL_TTF then, just an old accidental leftover?)

Nevermind, it seems like my SDL_TTF is just quite outdated
