I assume you did forget to add a "cd library-pkg" here.

With Git 1.7.1 I get the following error message:

fatal: '/tmp/library-pkg.git/library.git' does not appear to be a git repository
fatal: The remote end hung up unexpectedly
Clone of '/tmp/library-pkg.git/library.git' into submodule path 'src' failed

Which is rather what I would have expected: Using "./library.git src"
implies the library living *inside* the "library-pkg.git" repo, not
next to it (and the error message shows that). "../library.git" is the
correct relative path, so the next command works as expected.

Hmm, the documentation says "the location relative to the
superproject’s origin repository", not the directory containing
it. This means you have to use ".." first to get out of the
repository itself, no?
