/etc/env.d/99root contains: PATH=/opt/root/6.12/bin LDPATH=/opt/root/6.12/lib64 PYTHONPATH=/opt/root/6.12/lib This means the PATH will not be set for the root user, and hence not used by portage, causing packages such as sci-physics/vgm, sci-physics/genfit, sci-physics/geant-vmc from the science overlay to fail to find the installed root. In FindROOT.cmake, these packages look for the root-config binary in PATH. To fix this, changing /etc/env.d/99root to contain: PATH=/opt/root/6.12/bin ROOTPATH=/opt/root/6.12/bin LDPATH=/opt/root/6.12/lib64 PYTHONPATH=/opt/root/6.12/lib helps. This issue was "hidden" in previous packaging, since if root is installed to usual /usr/bin, this is already present in both PATH and ROOTPATH.

Sorry it took me so long to notice - but the fix is faulty, now PATH is not set anymore in the environment file. From the ebuild code: echo "PATH=${EPREFIX}/${MY_PREFIX}/bin" > 99root || die echo "ROOTPATH=${EPREFIX}/${MY_PREFIX}/bin" > 99root || die echo "LDPATH=${EPREFIX}/${MY_PREFIX}/$(get_libdir)" >> 99root || die The second "echo" recreates the file, hence the "PATH" setting.
... hence the path setting is lost (sorry, submitted too early). Likely, the best would be another revision bump after this to roll out the fix.
Re-opening this bug.
