I had a similar problem.  In my case, I had a target named data and wanted
an update target that would force rebuild of that target.  I solved it by
doing:

    data = env.Command(...)
    env.Alias("data", data)

    if "update" in COMMAND_LINE_TARGETS:
      env.AlwaysBuild(data)
      env.Alias("update", data)
