^cppyy uses a pre-built header file (PCH). This will be build/installed on installation time and/or first use. It will have the standard headers baked in. It looks like you have a different C++ compiler in your current environment from the one used to install cppyy; or you have old local prebuilt modules/dictionaries in the test directory.
For the former, the easiest fix is probably to force recompiling the PCH by setting the CLING_REBUILD_PCH envar to 1. (And unset it, after the PCH has been rebuilt.)
For the latter, simply run make -k clean in the test directory.
