dev-libs/boost-1.33.1 cannot be built using gcc-4.1.0 The problem is libboost_wserialization - for some reason it tries to build this sub-library. The build fails because of this problem: /var/tmp/portage/boost-1.33.1/work/boost_1_33_1/libs/serialization/build/../src/basic_text_wiprimitive.cpp:15:2: error: #error "wide char i/o not supported on this platform" And it is right, there is no std::wistream on my system.
