CheckFunction and SetFunction modules

Dear All experts,

I am trying to migrate a new server for asterisk version 1.4.44 but found that the modules CheckFunction / SetFunction are missing after I have installed the same version of asterisk in the new server.
When I tried comparing the modules loaded by:
CLI> core show applications

These two cannot be found:
CheckFunction: Check Function modules
SetFunction: Set Function modules

May I know how can I get the above 2 modules ready?

Many Thanks.
