./install_lua_modules.sh - The unauthenticated git protocol on port 9418 is no longer supported.

The install script fails. This appears to be due to a change by github.

This would be difficult to fix in the proper way as torch7 is not maintained.
You can work around this problem with the following commands.

# replace git:// with https://
git config --global url."https://".insteadOf git://
./install_lua_modules.sh
# restore git global config
git config --global --unset url."https://".insteadOf git://

That did seem to fix it however torch had other issues. I'm trying your version of torch instead.
