I understand, Peng. I didn't make my point very well. If there are so many ways to install something on a Mac, and MacPorts can only know about what it is responsible for, and you access that through the port command, it doesn't seem reasonable that by trying to execute some random command that MacPorts would understand what it is you are trying to do and what you should to rectify the situation. Debian Linux is built on top of APT and is designed to do what you are asking about. It's a very integral part of the system. MacPorts, while a wonderful add-on to Mac OS, isn't in the underpinnings of the operating system and can't know what you have on your system.
