You would "with" the package containing the procedure.

You seem to think that the Ada "with" mechanism is similar to the C
#include mechanism. It is not. The Ada "with" mechanism is designed to
specifically support separate compilation. You still need the package
specification to perform a "with" so that the compiler can check the
validity of your references to identifiers from the foreign package.

The ".ali" file is not helpful. It primarily specifies linker instructions.
It is a product of the GNAT compiler, not a source file used by the GNAT
compiler.
