During the installation the ebuild somewhere makes a chown foldingathome:foldingathome which fails because the group does not exist. The ebuild only creates the user. After groupadd foldingathome and emerging again, the installation worked. You can see the user creation and the error "chown: invalid group: ‘foldingathome:foldingathome’" here: * Adding user 'foldingathome' to your system ... * - Userid: 999 * - Shell: /sbin/nologin * - Home: /opt/foldingathome * - Groups: (none) * - GECOS: added by portage for foldingathome * - Creating /opt/foldingathome in / >>> Unpacking source... >>> Unpacking fahclient_7.5.1-64bit-release.tar.bz2 to /mnt/ramdisk/portage/sci-biology/foldingathome-7.5.1/work >>> Source unpacked in /mnt/ramdisk/portage/sci-biology/foldingathome-7.5.1/work >>> Preparing source in /mnt/ramdisk/portage/sci-biology/foldingathome-7.5.1/work/fahclient_7.5.1-64bit-release ... >>> Source prepared. >>> Configuring source in /mnt/ramdisk/portage/sci-biology/foldingathome-7.5.1/work/fahclient_7.5.1-64bit-release ... >>> Source configured. >>> Compiling source in /mnt/ramdisk/portage/sci-biology/foldingathome-7.5.1/work/fahclient_7.5.1-64bit-release ... >>> Source compiled. >>> Test phase [not enabled]: sci-biology/foldingathome-7.5.1 >>> Install sci-biology/foldingathome-7.5.1 into /mnt/ramdisk/portage/sci-biology/foldingathome-7.5.1/image/ chown: invalid group: ‘foldingathome:foldingathome’ * ERROR: sci-biology/foldingathome-7.5.1::gentoo failed (install phase): * fowners failed The group is not created and the user is not member of any group as it seems.
