Well, for the same reason that not all modules within a Mercury project
have one. The purpose of the main predicate in Mercury is the same as
the purpose of the main-function in C. It's were the execution of the
program starts. 
So, why should there be a main predicate in a library file? The purpose
of a library file is to provide predicates which can be used in a
program. The main-predicate is therefore expected to be located in the
user modules, not in the library modules.
