As Daniel said, yes, you can change the prefix -- but not by editing macports.conf. (Thus I'm not sure why the prefix is even listed in macports.conf.) To change the prefix, you must build MacPorts from source and pass your desired prefix to the ./configure script.

e.g.

./configure --prefix=/opt/mymacports --enable-readline
make
sudo make install
