Установка "Vbox" .....точнее как и под каким соусом ..[solved]

Устонавливал app-emulation/virtualbox-ose-3.1.2 (gcc 4.3.4) соответственно не вышло : читал что нужно gcc ниже версии брать.. , а может все-таки нашлось решение ?
PS какой лучше gcc выбрать на этот момент или все так же ?

Hardening is enabled which means that the VBox binaries will not run from
the binary directory. The binaries have to be installed suid root and some
more prerequisites have to be fulfilled which is normally done by installing
the final package. For development, the hardening feature can be disabled
by specifying the --disable-hardening parameter. Please never disable that
feature for the final distribution!
