"pkg-config not found" error when trying to build makedepend (needed for Xorg).

I'm trying to build makedepend from here:, but when I run configure I get the this error
configure: error: The pkg-config script could not be found or is too old.  Make sure it
is in your PATH or set the PKG_CONFIG environment variable to the full
path to pkg-config.

Alternatively, you may set the environment variables X_CFLAGS
and X_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

I do not have pkg-config installed.
I could not find pkg-config in the LFS 7 book at all, but it is in the LFS 7 rc1, so I tried the instructions from LFS 7 rc 1 (, but when I run make I get this error

Because you don't have glib installed. pkg-config prior to version 0.26 shipped with a copy of glib.h that was sufficient to build pkg-config. That is not the case with 0.26. If you follow the pkg-config instructions in the stable BLFS documentation, it will tell you glib is a dependency.

On the other hand, makedepend is not required to install Xorg if all you want is a GUI (at least it didn't used to be). Of course, you will need glib if you plan to use GTK2.
