Sorry, my bad, the error was a wrong ccache umask in make.conf which caused the requested library from the cffi ebuild was installed with insufficient priviledges. The file permission for group "others" was 0. # ls -l /usr/lib64/python3.6/site-packages/_cffi_backend.cpython-36m-x86_64-linux-gnu.so -rwxrwx--- 1 root root 169072 Feb 5 17:06 /usr/lib64/python3.6/site-packages/_cffi_backend.cpython-36m-x86_64-linux-gnu.so This caused the error, now commented in my make.conf: #CCACHE_UMASK=007
