If Cons is executing a command every time you run it, and that's not
what you want, the most likely cause is that the executed command does
not create the target file specified.  As a trivial example:

        $env->Command('.always', 'input', "cat input > output");

Will *always* run the "cat input > outfile" command because the .always
file is never created by it.  Take a look at the target file specified
for your "pkgmk" call.

Beyond that general advice, additional details would help.
