The configure phase of app-emulation/spice-0.11.0 (with the 'client' USE flag disabled) fails if media-libs/alsa-lib isn't present: [...] checking for CELT051... yes checking for pyparsing python module... found checking for ALSA... no configure: error: Package requirements (alsa) were not met: No package 'alsa' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables ALSA_CFLAGS and ALSA_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. According to the ebuild, media-libs/alsa-lib is only added to RDEPEND if the 'client' USE flag has been set. Manually installing media-libs/alsa-lib beforehand fixes the issue, however the resulting libspice-server.so library doesn't seems to link to an alsa lib, therefore it might also be an upstream configure problem. Steps to reproduce: emerge --unmerge media-libs/alsa-lib echo "app-emulation/spice -client" >> /etc/portage/package.use emerge -va "=app-emulation/spice-0.11.0"
