The automated FreeBSD package building with poudriere produced the same error
last night for FreeBSD 10.3.

Since about a year the port uses a mixture of clang and gcc because clang does
not support global register variables. On the other side building all
ports with clang
but only vbox with gcc created issues in KDE.

The result are a couple of patches from jkim which are not supported
at all but use
both compilers in a mix. Might be they need to be fixed after the
update to vbox 5.0.
