textproc/fop doesn't build

[Eric Will]

checking for XEXT... configure: error: Package requirements (xproto >= 7.0.13 x11 >= 1.1.99.1 xextproto >= 7.1.99) were not met:
gnome-config: not found
No package 'xproto' found
gnome-config: not found
No package 'x11' found
gnome-config: not found
No package 'xextproto' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables XEXT_CFLAGS
and XEXT_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/libXext/work/libXext-1.3.0/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`).
