Postgres-XL cluster

I'm trying to create a Postgres-XL cluster on 4 servers. I've followed the recipe on https://ruihaijiang.wordpress.com/2015/09/17/postgres-xl-installation-example-on-linux/ (Note: update to *pgxc_ctl.conf* by adding tmpDir=/tmp and localTmpDir=$tmpDir) I get to pgxc_ctl init all and then the following error: postgres@ls $ pgxc_ctl init all /bin/bash Installing pgxc_ctl_bash script as /home/postgres/pgxc_ctl/pgxc_ctl_bash. Installing pgxc_ctl_bash script as /home/postgres/pgxc_ctl/pgxc_ctl_bash.
