Can't load linux compatibility layer in jail

[pdx_beagle]

Hi all,
I'm a newbie to FreeBSD, but am enjoying learning. I've been running into a problem trying to install the SpiderOak port in a new jail. After creating a brand-new jail and assigning storage, when I try to enable the linux compatibility layer: "kldload linux" I get the following error:

kldload: can't load linux: Operation not permitted

I have been unable to find any relevant information about this error, and can't successfully proceed with the install without linux emulation. I am on the latest version of FreeNAS as of today: FreeNAS-9.3-STABLE-201511040813 Any tips or solutions from the gurus out there would be appreciated!

Linux jails were removed in 9.3-RELEASE for their tendency to not work and the disproportionate amount of support headaches they caused, IIRC.
