Another solution is to use  \AtBeginDocument
to run a test to see whether there is any need to
define this command. Since all packages will have
been loaded at this time, it is sufficient to use
  \@ifpackageloaded  for this check.
Only if the package was not loaded, do you need
to define for yourself the macro that you require.

This strategy completely resolves such package-order
dependency problems.
