Comment (by tamas.fulop@…):

 Thank you for the additional information. Now the difficulty is clearer
 (the shell script I would write to automatize this process should make no
 mistake). Reinstalling all the ports will be safer.

 Upgrading the OS (especially by four versions) would break so many things
 and would set back my productivity so considerably that I always do it
 only when support for the current OS has died out comparably seriously.
 (For my type of work and usage, OS 10.3 was already satisfactory...)
 Nevertheless, thank you for your suggestion.
