This problem may occur in other virtualbox-guest-additions. I am working with virtualbox-guest-additions-6.0.14. If, in a gentoo virtualbox VM, I emerge virtualbox-guest-additions-6.0.14 and then unmerge the package, not all files installed by the emerge are removed. I don't if this is by design or is a bug in the ebuild. Reproducible: Always Steps to Reproduce: 1.emerge virtualbox-guest-additions 2.emerge --unmerge vitualbox-guest-additions 3.

This is actually by design: since your system might fail to boot with the kernel for which the external modules were compiled, these modules are not registered as part of the package they were installed by. Cleaning up is left as an exercise for the admin.
