You need to be sure to instantiate both at the same time since a 
class needs to do some introspection on its related class (to find 
the ID field and such).

The best way to do this is read all your configurations into a 
single hashref and process them all at once. For instance, the 
following should work assuming that 'read_config()' returns a single 
hashref with the configuration for a single object.

  my $config_package_a = read_config( 'conf/package_a.perl' );
  my $config_package_b = read_config( 'conf/package_b.perl' );
  SPOPS::Initialize->process(
            { config => { a => $config_package_a,
                          b => $config_package_b } } );

Hope this helps,

Chris
