You should not do it that way.  First, when building on the cluster, you
only have network access during the *fetch targets.  Second, you should
fetch all the different submodules by URL, and move them at the right place
in post-extract, or something, see sysutils/consul for example.  I know,
it's aweful, but it's how it should be done for now.
