This looks like the virtualbox ebuild is executing some tests, especially considering that the executable is named "tstVMStructRC". @Lars: Is my assumption right? If it is, the ebuild should disable those tests unless the user requests them -- there wouldn't be any selinux problems if the ebuild wasn't trying to execute virtualbox at compile time.
On my system tstVMStructRC is no longer being built. Does this issue still occur? Tested in 7.0.2.
