The man page of finger (from =net-misc/netkit-fingerd-0.17-r3) says that the users home directory needs to be world-executable for the .nofinger file to be found by finger, which is correct. It also says in parenthesis (o+w), which would not set the execute bit, but the write bit for everyone.
I'm attaching a patch that fixes the typo.
I have tried submitting this upstream, but the mail address given in the README bounces (firstname.lastname@example.org). As far as I understand, netkit is orphaned.
