Arch Linux

Description:

When I try to build Qt 5.4 rc it fails with the following message

Got keys from plugin meta data ("xcb")
loaded library "/usr/lib/qt/plugins/platforms/libqminimal.so"
QLibraryPrivate::loadPlugin failed on "/usr/lib/qt/plugins/platforms/libqminimal.so" : "Cannot load library /usr/lib/qt/plugins/platforms/libqminimal.so: (/usr/lib/qt/plugins/platforms/libqminimal.so: undefined symbol: _ZNK15QPlatformScreen11pageFlipperEv)"
This application failed to start because it could not find or load the Qt platform plugin "minimal".

Available platform plugins are: eglfs, kms, linuxfb, minimal, minimalegl, offscreen, xcb.

Reinstalling the application may fix this problem.

This means /usr/lib/qt/plugins/platforms/libqminimal.so lacks some library. What library?
Additional info:
qt5-base 5.3.2-2 x86-64

Steps to reproduce:

export QTDIR="${srcdir}"/qt5
export LD=g++
export LD_LIBRARY_PATH="${QTDIR}"/qtbase/lib:"${QTDIR}"/qttools/lib:"${LD_LIBRARY_PATH}"
export QT_PLUGIN_PATH="${QTDIR}"/qtbase/plugins
