This is the problem. The .gitmodules entry in nacl.git uses an absolute path (or URI in this case) for the submodule. Git does exactly what it should and tries to clone it.

The solution to this is to use a relative path[1] in .gitmodules (either edit it by hand or do git rm & git submodule add). Note that by using a relative path it assumes that the parent and submodule repositories are hosted in the same location (which may or may not be true for your use-case).

-- [1] - see the 3rd paragraph for the add command in https://git-scm.com/docs/git-submodule
