The generator should return an Action or something that can be turned
into an Action.
See http://www.scons.org/doc/HTML/scons-user/x3755.html

The only things that can be turned into Actions are a string (which is
a command to be executed), or a python function (which gets run when
the action is executed), or lists thereof.

(see http://www.scons.org/doc/production/HTML/scons-api/index.html if
you really care.)
