Requested 'xproto >= 7.0.17' but version of Xproto is 7.0.16

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

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

===>  Script "configure" failed unexpectedly.
Please report the problem to x11 at FreeBSD.org [maintainer] and attach the
"/usr/ports/x11/xprop/work/xprop-1.2.1/config.log" including the output of
the failure of your make command. Also, it might be a good idea to provide
an overview of all packages installed on your system (e.g. an `ls
/var/db/pkg`).
