Note that the uninstallation can mark new ports as leaves.

To uninstall all leaves, you have to repeat the process until the
port echo leaves
command comes back empty.

To simplify this, consider installing the port_cutleaves port and running
sudo port_cutleaves

I don't know, but why do you want to know that?

Your installed ports are there either because you requested them (you need and 
care about these ports), or because something you requested needed them (you 
indirectly need but don't directly care about these ports), or because they're 
left over from something that used to be installed that needed them (you don't 
need or care about these ports).

You're asking if there's a way to list the port you need but don't care about. 
I'm not sure if there's a command for that.

You can use "port installed requested" to see the list of ports you requested. 
If anything in the list is not something you actually want, you can mark it as 
not requested by using "sudo port unsetrequested PORTNAME".

You can use "port installed leaves" to see the list of ports you didn't request 
that aren't needed by anything. If anything in the list is something you 
actually want, you can mark it as requested by using "sudo port setrequested 
PORTNAME".

Finally, you can uninstall the ports you really don't need by using "sudo port 
uninstall leaves".
