Install pkg for FreeBSD 10

I'm getting the following error while trying to install pkg on FreeBSD 10.4- Bootstrapping pkg from pkg+http://pkg.FreeBSD.org/FreeBSD:10:amd64/latest , please wait... pkg: Error fetching http://pkg.FreeBSD.org/FreeBSD:10:amd64/latest/Latest/pkg.txz : Not Found A pre-built version of pkg could not be found for your system. Consider changing PACKAGESITE or installing it from ports: 'ports-mgmt/pkg'. When I try to install it using ports, I get the following error- set: Illegal option -o pipefail ===> Options unchanged set: Illegal option -o pipefail *** Error code 2 Stop. make[1] : stopped in /data/usr/ports/ports-mgmt/pkg *** Error code 1 Stop. make: stopped in /data/usr/ports/ports-mgmt/pkg Is there any other way to install pkg or change default repo URL to download packages?
