With that specific setup, I am not sure.  But if you are willing to change
a couple of things you can do:

-- my_program_package.ads
package My_Program_Package is
   -- Notice no declaration here for the procedure, but you can put other
   -- things if you like
end My_Program_Package; 

-- my_program_package-program_entry_procedure.adb
procedure My_Program_Package.Program_Entry_Procedure is
begin
   -- your main stuff
end My_Program_Package.Program_Entry_Procedure;

Then you modify the GPR file to point to it as the main:
for Main use ("my_program_package-program_entry_procedure.adb");

I do something similar for my Gnoga GUI projects so I can have
program level stuff in the top package but have the main a child
of that top level package.
