app-emulation/virtualbox-ose-3.2.0 fails to build with gcc-4.5.0. It appears that it is using -Werror (or equivalent) to make all warnings errors. Unfortunately, there are some warnings which stop it from compiling.

The upstream bug tracker seems to have some patches in it for gcc-4.5: http://www.virtualbox.org/ticket/6715, seems the recommended solution is the following: To workaround the -Werror issues you can add VBOX_WITH_WARNINGS_AS_ERRORS := to a file LocalConfig.kmk which you put into the root directory of your tree.
