I don't know how to compare pkg-plist files? How to make decision a port 
  is older version and not variant of current one? It must be some 
evristic method. Some files can be moved in other place, some files can 
be new, some files can be moved away in new version.
In port's variant case path can be changed or file name can be changed 
(libsome.so and libsome_r.so).

In other words, I can't image how it's possible.

It's more easy to image :)
