This is not correct, it shouldn't use world-c++. This is mine:

CMake 2.6-0, Copyright (c) 2007 Kitware, Inc., Insight Consortium
C compiler on this system is: cc -O2 -fno-strict-aliasing -pipe 
-march=athlon-mp
C++ compiler on this system is: c++ -O2 -fno-strict-aliasing -pipe 
-march=athlon-mp

I think you should check why it's failing for you, but it's not a common 
behavior, so I don't see the reason to handle NOCCAHE inside the ports 
infrastructure.
