That's likely due to the time those functions got introduced in Tcl...
I actually thought they were in Tcl8.x, but it seems necessary that x
>= 1. The functions are used extensively, so an upgrade of Tcl/Tk is
suggested. 

[Poking a bit around reveal that Tcl_SetVar2Ex was Tcl_SetVar2 in 8.0
and the Get versions similar, but I can't seem to locate anything
about Tcl_GetString.]
