You have a problem here unrelated to your desire to re-write the
module. You are declaring subroutines in the package main, but trying
to call them in package mainprog. Perl won't be able to find those
subroutines regardless.
Your problem that actually has to do with the question is that you're
using 'use'. 'use' happens at compile time. That means it happens
long before the code that re-writes callbacks.pm is executed. You
need 'require' instead.
perldoc -f use
perldoc -f require
