gcc48 error on Mavericks

There is another problem regarding to the coexistence of xcode gcc and
gcc48 from macports.
When I do  "port select gcc mp-gcc48" , I can compile using "g++". But when
I switch back by "port select gcc none",
I got the error:

> g++ -g -o HelloWorld HelloWorld.cpp

-bash: /opt/local/bin/g++: No such file or directory

But strangely, when I do "which g++",  I get "/usr/bin/g++". Then why "g++"
still try to involve "/opt/local/bin/g++" but not "/usr/bin/g++"?
