When trying to install sci-chemistry/avogadro2, sci-libs/coinor-utils-2.9.11 emerges as a dependency. However, its compilation fails this way: === make[3]: Entering directory `/var/tmp/portage/sci-libs/coinor-utils-2.9.11/work/coinor-utils-2.9.11_build' PKG_CONFIG_PATH="/usr/lib64/pkgconfig:/usr/lib/pkgconfig:/usr/share/pkgconfig:/usr/lib64/pkgconfig" \ "x86_64-pc-linux-gnu-pkg-config" --libs coinutils > /var/tmp/portage/sci-libs/coinor-utils-2.9.11/image//usr/share/coin/doc/CoinUtils/coinutils_addlibs.txt Package coinutils was not found in the pkg-config search path. Perhaps you should add the directory containing `coinutils.pc' to the PKG_CONFIG_PATH environment variable No package 'coinutils' found make[3]: *** [install-data-hook] Error 1 ... ===
Are you using sci-libs/coinor-utils from the overlay or the tree?
Please add full build.log.
