You need to import the proper libraries and modules:

module: dylan-user

define library hello-world
  use common-dylan;
  use io;
end library;

define module hello-world
  use common-dylan;
  use format-out;
end module;

You need to import the module common-extensions, which makes the
above:

define library hello-world
  use common-dylan;
  use io;
end library;

define module hello-world
  use common-dylan;
  use common-extensions;
  use format-out;
end module;

Yes, 2.3.4 is a bit outdated.

Could you post the code for comparison please?  It's hard to say
whether that's an oversight in your code or the compiler without
seeing the code.
