 I encountered the same issue a few months ago and have found that if I
 uninstall devel/binutils or tweak my $PATH so that the base system's
 binutils (/usr/bin/ld, etc.) can be found first, the kernel modules
 from virtualbox-ose-kmod build and load successfully.
 
 If your system also has devel/binutils installed, try moving
 /usr/local/bin in your PATH environment variable to somewhere after
 /usr/bin and rebuild and reinstall virtualbox-ose-kmod.

 Perhaps the same tweak also works for them. Give it a try and see.
 
 Hope this helps.
