Created attachment 295029 [details] emerge --info and build log I was rebuilding media-libs/phonon-4.5.0 since the xine use flag is now forced off. I got the following build error: [ 54%] Building CXX object phonon/CMakeFiles/phonon.dir/pulsestream.cpp.o /tmp/portage/media-libs/phonon-4.5.0/work/phonon-4.5.0/phonon/pulsestream.cpp: In member function ‘void Phonon::PulseStream::setVolume(const pa_cvolume*)’: /tmp/portage/media-libs/phonon-4.5.0/work/phonon-4.5.0/phonon/pulsestream.cpp:84:65: error: ‘pow’ was not declared in this scope I suspect this can be solved by the addition of: #include <math.h> at the top of pulsestream.cpp
It looks like this is exactly the same thing as in bug #386489 (which was fixed, until just recently).
