fixesproto4: xorgproto-2018.4 PLIST conflic

[ng0%n0.is@localhost]

Hi,

in my sandbox pkgsrc currently does not build
some early dependencies of firefox and others.

In the case of fixesproto4 it can be build succesfully
but in make package logs the message below and fails.

=> Creating binary package /pkg_comp/work/pkg/x11/fixesproto4/work/.packages/fixesproto-4.0nb1.tgz
pkg_add: Conflicting PLIST with xorgproto-2018.4: include/X11/extensions/xfixesproto.h
pkg_add: 1 package addition failed


This is on NetBSD/amd64, native Xorg (not modular).
