Bug #12351: ruby-1.9.3.4 (Ubuntu): undefined variable in MiniTest::Unit::Runner::Worker (unit.rb:328)

----------------------------------------
An undefined variable in `MiniTest::Unit::Runner::Worker` causes `rake` execution to fail (status code 1) when performing tests. (Test case was running rake with code from https://github.com/blackducksoftware/ohloh_scm).

The cause is attempting to use an undefined class variable `@@installed_at_exit` on method `autorun` of class `Worker`. Possible solution: change

```ruby
at_exit {
# ...
} unless @@installed_at_exit
```

to

```ruby
at_exit {
# ...
} unless (defined?(@@installed_at_exit) and @@installed_at_exit)
```

Attachment (unit.rb.patch) is a diff patch for the affected file.

This affects Ubuntu 14.04 and related distributions (Lubuntu). Reported downstream as [Ubuntu Bug 1578547](https://bugs.launchpad.net/ubuntu/+source/ruby1.9.1/+bug/1578547).
