Is linux compatibility layer possible inside a jail?

[stuck]

Hi I know this topic is frowned upon, but I'm just trying to setup a low power consumption box for home to do a couple of things…
I have installed pfsense 2.0.3 x64 on a D2500CC board.  But I also need it as an always-on box to backup my samba share to crashplan...
My samba share is mounted on a dd-wrt AP using optware...
In order to do this, I need linux compatibility layer on the pfsense box.  So I was searching for a way to do this inside ezjail...
I'm following this guide: http://blog.oddbit.com/post/installing-crashplan-under-freebsd-8

Any help or suggestion is greatly appreciated
