Trouble Installing Virutual Box Guest Additions

Im on OSX Mavericks using Virtual Box. I installed Kali Linux, updated, upgraded, installed dkms, all updates available in SoftWare Update, and installed current headers and restarted. Im also logged in as root.

I inserted the guest additions cd and copied VBoxLinuxAdditions.run to another folder, chmodded it 755 and tried to run it. It runs but it continuously says

Code:

---

Building the shared folder support module FAILED
(Look at /var/log/vboxadd-install.log to find out what went wrong)

---

Im using the virtual box provided by the devices>install guest additions


Can someone tell me whats wrong? I attached the log file. Thanks
