No, there isn't, sorry. The installation path is hardcoded all over  
the installed files.

Installing as binary packages would make the MacPorts on the machine  
you install onto unaware of their existence and they would collide  
with any ports you later want to install on that machine. So I cannot  
recommend this procedure.
