Problem seems to occur when the file /usr/share/qt4/mkspecs/qconfig.pri has modification time in the future. Workaround is to set your system clock to a value where that file doesn't have a modification time in the future, qt-xmlpatterns then compiles just fine. Reproducible: Always Steps to Reproduce: 1. Set back the system clock >6h 2. emerge =x11-libs/qt-xmlpatterns-4.6.2

Is there anything special about /var/tmp you're not telling us?
Nothing special about it. It's on the root partition. You don't have this behaviour?
I think this falls under the category of "well, don't do that then"...
