>Description:
pkgsrc currently has x11/Xfixes in version 2.0.1 which is outdated (current version  libXfixes-5.0.2, http://www.linuxfromscratch.org/blfs/view/svn/x/x7lib.html)

The newer libXfixes is required for libXi to be used (Xinput2) with Qt 5.6, the older one leads to compile errors on the configure tests of Qt5 due to the missing declaration of "PointerBarrier".

Please update the port to make libXi usable in Qt 5.6
>How-To-Repeat:
-download Qt 5.6
- run ./configure -v
- inspect the output for Xinput2 detection

To see the error, do pkgin install libXi Xfixes for the dependencies.
>Fix:
Update the Xfixes port to the newest version
