cannot find libmutter while building gnome-shell module

[Tim Cuthbertson <tim gfxmonk net>]

I have done a "jhbuild"; everything else seems to be up to date (and I
specifically did a build on mutter, just in case). I presume libmutter
is supposed to be built by the mutter module inside
~/gnome-shell/source/mutter/?

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

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