>Description:

        Building x11/libxcb on netbsd-4 fails with an undeclared
        dependency on "xau" -- whatever that is; a find(1) on the
        pkgsrc tree comes up empty. My guess is that the package was
        built and committed on an xorg system, without checking for
        backward compatibility.

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

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

*** Error code 1
