After upgrading to sys-apps/attr-2.4.48 I get an error like: mv: relocation error: /lib64/libacl.so.1: symbol getxattr, version ATTR_1.0 not defined in file libattr.so.1 with link time reference Since this affecting coreutils it effectively bricks the system as portage will no longer be able to install a package even from a saved binary one. Note that objdump on libattr.so.1 shows that version ATTR_1.0 is still present, probably just missing that symbol: Version definitions: 1 0x01 0x0c7a2aa1 libattr.so.1 2 0x00 0x09982870 ATTR_1.0 3 0x00 0x09982871 ATTR_1.1 ATTR_1.0 4 0x00 0x09982872 ATTR_1.2 ATTR_1.1 5 0x00 0x09982873 ATTR_1.3 ATTR_1.2

attr-2.4.48-r1 provides a compat xattr.h, and acl-2.2.53 doesn't use attr/xattr.h so this should be all set
