there is in fact 2 distinct problems :

GCC changes from 3.3 to 3.4 means that a clean compile is needed.
10.4 introduced a new libc++ which need some stubs libs for  make  
compile and not scons, + ranlib operations have changed

I've not yet get clean compile with gcc 3.4, and wont likely do it  
now, as a gcc 3.4 compile would likely not run on 10.3 (due to the  
missing stubs)

and changes to C++ ABI (again)

the easiest solution is to use gcc-select to set compiler to 3.3
