Created attachment 494756 [details] Fixed ebuild The ebuild of dev-libs/double-conversion-2.0.1 contains a sed command, which causes the ebuild to die, whenever the CXX path contains a slash (/). A patch is provided below.
This bug can be reconstructed by setting CXX="/usr/bin/g++" in /etc/portage/make.conf I simply replaced the line sed -i -e "s/g++/$(tc-getCXX)/" SConstruct || die to sed -i -e "s@g++@$(tc-getCXX)@" SConstruct || die
3.0.0 gets rid of scons, hence no sed anymore.
2.0.1 is long gone.
