Title: Test suite fixes

Three fixes, the first is that on zsh echo is an built-in so the cmd.which test failed with
```AssertionError: '/bin/echo' != 'echo: shell built-in command'```

The second is that gem/rvm tests used patch.object in a way that isn't supported in mock 0.7, giving
```TypeError: _patch_object() got an unexpected keyword argument 'return_value'```

The third one skips the pip test if pip is not installed.
