After compiling and installing graphics/xpdf4 on a host without desktop environment, the xpdf command produce the following output and does not accept any keyboard input.
xkbcommon: ERROR: failed to add default include path /usr/local/share/X11/xkb
Qt: Failed to create XKB context!
Use QT_XKB_CONFIG_ROOT environmental variable to provide an additional search path, add ':' as separator to provide several search paths and/or make sure that XKB configuration data directory contains recent enough contents, to update please see http://cgit.freedesktop.org/xkeyboard-config/ .
The error message was right as /usr/local/share/X11/xkb was empty. After installing x11/xkeyboard-config xpdf stoped emiting that message and correctly accepted keyboard input. xpdf is so far the only command affected.
A dependency on x11/xkeyboard-config is obviously missing in x11-toolkits/qt5-gui. The dependency could alternatively be set on the x11/libxkbcommon port.
Hmm, I think it makes more sense to make libxkbcommon have a run-time dependency on xkeyboard-config.
libxkbcommon's PACKAGING says:
- (build optional, runtime) xkeyboard-config.
During build, for automatically detecting the value of
-Dxkb-config-root instead of guessing (/usr/share/X11/xkb).
During runtime, not strictly needed, but most users of the library
would need it.
while its README.md says:
libxkbcommon does not distribute a keymap dataset itself, other than
for testing purposes. The most common dataset is xkeyboard-config, which
is used by all current distributions for their X11 XKB data.
Arch Linux, Fedora, openSUSE and Debian already have this dependency in their packages.
The suggestion to add a xkeyboard-config run dependency to libxkbcommon makes
a lot of sense to me. I had to add an xkeyboard-config dependency to kodi-devel
too in ports r490630 to workaround this issue here.
Can we get some x11@ feedback here ASAP please? This is broken and easily

x11/libxkbcommon: Add dep on xkeyboard-config
Add a run time dependency on x11/xkeyboard-config in x11/libxkbcommon.
While not strictly necessary, this is recommended upstream, since almost all
uses of libxkbcommon also needs xkeyboard-config. This is similar to how it
is done in other distributions.
This solves issues when graphics/xpdf4 is installed without a desktop or
graphical environment, as well as other places.
