No, neither of them exists.

Looks like, plugin gets installed before the components and since that file is required, it throws an error.

That's strange, because the plugin shouldn't be loaded until all the files are copied.
Since we have no other reports of such problem yet and I don't know what else could cause it if directory permissions are OK, it seems like some problem with your server's configuration. In such case I can only offer you our paid support to check what exactly is the problem on your server: www.artio.net/e-shop/support-services/joomla-related-support-1h
