According to this blog post, modules should be installed in the root library. However, the wiki implies here that the appropriate path might look like "/Users/username/Library/Application Support/Titanium/module.zip".
In my experience, the root path should be used or the module should be placed in the actual app's folder.
Thank you for bringing this to our attention. You are quite right, the blog post is correct. I will resolve the problem with the Titanium Studio documentation.
