In both /sbin/arptables-save and /sbin/arptables-restore, you will find the following line: my $tool = "__EXEC_PATH__/arptables"; __EXEC_PATH__/ should be /sbin/ Reproducible: Always Steps to Reproduce: 1. emerge arptables 2. /sbin/arptables-save Actual Results: it prints "ERROR: Tool __EXEC_PATH__/arptables isn't executable" Expected Results: It should have been able to find the tool. I will attach a patch that fixes these paths.
