you can "ignore" search paths for the scanning phase (detecting implicit dependencies) by not adding them to the CPPPATH variable. 
Instead you have to provide your own "-I<path>" flags to CXXFLAGS, or similar for shared objects/libs.
See the "CPPPATH trick" at http://scons.org/wiki/GoFastButton ...
