So I discovered one way to achieve this (though probably not optimal at all
...) using LoadError so that if the dated vagrant gem is uninstalled, the
Rakefile will add the [deb,rpm] package paths and attempt again.
Comments/Alternate suggestions more than welcome ...
+
require 'rbconfig'
require 'rubygems'
-require 'vagrant'
+begin
+ require 'vagrant'
+rescue LoadError
+ VAGRANT_PKG_REQ_PREFIX = "*/opt/vagrant/embedded/gems/gems/*"
+ puts "vagrant library require files from gem not found, attempting
vagrant [deb,rpm] package require paths under #{VAGRANT_PKG_REQ_PREFIX}"
+ Dir.glob("#{VAGRANT_PKG_REQ_PREFIX}*/lib").each do |pkg_req_dir|
+ $LOAD_PATH.unshift File.expand_path("#{pkg_req_dir}", __FILE__)
+ end
+ # attempt to load vagrant library again, this time failing by terminating
+ require 'vagrant'
+end
require 'uri'
