Bug 187260

x11-toolkits/qt5-gui fails to build with the error:

input/evdevmouse/qevdevmousehandler.cpp:56:10: fatal error: 'linux/kd.h' file not found
#include <linux/kd.h>

I fixed this by replacing the header with <sys/kbio.h>, I lifted this solution from graphics/svgalib, which I found after a little grepping.

Then I get this error:

This seems to be defined in /usr/local/include/xcb/xkb.h, which is part of x11/libxcb; I have the latest version installed (1.9.3).

I fixed this by adding:
-lxcb-xkb
to /src/plugins/platforms/xcb/Makefile.xcb-plugin in the LIBS variable

After this, build & install seem to work okay.

Sorry for not providing a patch to fix this in the port. :-( I have a number of other things I *really* need to get done, and it's been ages since I did anything serious with the port system & CMake...
