I have seen a similar thing trying to compile lmms with gcc46. From what 
I can tell the linker has brought in a gcc42 version with another lib 
which prevents the newer gcc46 version coming in.

I haven't got around to working it out but thought of looking through 
external libs used to find the one that brings in the older version and 
building that with gcc46. I also wonder if a static linked c++ lib may 
be preventing the newer version being brought in.
