Indeed, and I added a note today to that ticket to mention the points I made below as soon as I noticed that. 

> And if I do _not_ change the name, then how will command “sudo port install okular” know to use the modified port, inside my home tree, instead of the distributed one?

If I am not mistaken, the order in which you define your sources in sources.conf determines which one supersedes the other (to have your local one superseding, put it before the main one). 
To be sure of which one you use, you can also increase the revision to check the version of the installed port. 

And again, I just don’t recommend it, but you can use the name okular2. You just have then to be consistent in the name used in the Portfile itself. 

Cheers, 

Nicolas
