That will not work as-is.  It will only look at the host's package 
database.  To check the jails, see the pkg-version(8) man page about the 
PKG_DBDIR environment variable.  Set that to the jail's package database 
directory, like /usr/jails/myjail/var/db/pkg, and then pkg-version will 
check the jail's packages.
