This website provides an instant Ubuntu 13 server: http://instantserver.io So it's a standard bare-ish install. Getting a server and then checking out supercollider fails:

$ sudo apt-get install git [...] $ git clone --recursive https://github.com/supercollider/supercollider.git [...] remote: Total 351 (delta 237), reused 330 (delta 216) Receiving objects: 100% (351/351), 73.50 KiB, done. Resolving deltas: 100% (237/237), done. Submodule path 'external_libraries/nova-tt': checked out 'ba36110f89a5f5e72e839019c85c480115446f65' No submodule mapping found in .gitmodules for path 'boost_lockfree' Failed to recurse into submodule path 'external_libraries/nova-tt'

It should not fail. People have raised this issue before, and been told how to fix it on their system. Do not tell me how to fix it on my system after this error. People should be able to clone SC from scratch without errors. Do we need to:

1. fix something in the git repo?
2. tell people a different git command?

I don't understand git-submodules metadata... grepping for 'boost_lockfree' finds nothing suspicious, so why is it looking for it?
