~/.rvm/scripts/hook: line 17: rvm_hooks_path: unbound variable

Description

We are sequencing genomes, for the purpose of understanding the causes of various terminal diseases, using a custom ruby-based pipeline of software with RVM 1.25.28 and ruby 1.9.3p448. RVM, ruby, and all other dependencies, exist on a NFS-exported home directory across a group of servers. We can run our pipeline successfully on the older RHEL 6.3 servers. I built a new CentOS 6.8 server where we cannot now run the pipeline. When we have "set -o nounset" included on this Centos 6.8 server, it dies immediately with the error:

/home/aladdin/.rvm/scripts/hook: line 17: rvm_hooks_path: unbound variable

However jobs run successfully on the older RHEL 6.3 server with that option in place.

Though they do run on the CentOS 6.8 server with that option removed...

Do you have any idea on case given RVM, ruby, bash, and all other dependencies are the same across these servers given the shared NFS directory?

Steps to reproduce

CentOS release 6.8 (Final)
2.6.32-642.13.1.el6.x86_64

1. qsub file which calls ruby
2. immediate crash shown below

aladdin@epicore07 scratch001 $ cat /home/aladdin/.rvm/scripts/hook

#!/usr/bin/env bash

# need additional step to not redefine variables value if already set

if
  [[ -n "$rvm_hook" ]]
then
  hooks=( "$rvm_hooks_path")
  [[ "$PWD/.rvm/hooks" == "$rvm_hooks_path" ]] || <------ LINE17 HERE
    hooks+=( "$PWD/.rvm/hooks" )

  _hooks_list=($(
    __rvm_find -L "${hooks[@]}" -iname "$rvm_hook*" -type f 2>/dev/null
  ))

  for hook in "${_hooks_list[@]}"
  do
    if [[ -x "${hook}" || "${hook##*/}" == "$rvm_hook" ]]
    then
      rvm_debug "Running $hook"
      __rvm_conditionally_do_with_env . "${hook}" >&2
    fi
  done
fi

In ~/.rvm/scripts/initialize I see:

 case "$rvm_path" in
    (/usr/local/rvm)         rvm_user_install_flag=0 ;;
    ($HOME/*|/${USER// /_}*) rvm_user_install_flag=1 ;;

So why unbound?

Expected behavior

The jobs run in SGE

Actual behavior

Immediate crash
