You may need to restart the Window System (or just restart the guest system)
to enable the Guest Additions.

I can reproduce the build error. Will see if it can be fixed ...

Thanks to the work of Pablo Greco, it was found that the build errors were due to missing header files. I filed a bug report #18249 and submitted a patch.

News! The latest test build, VBoxGuestAdditions_6.0.1-128006, has fixed the issue.

Thanks for confirming @toracat! Marking as [Fixed].

The latest test build, VirtualBox-6.0.1-128018-Linux_amd64, has fixed the issue : "vbox fails to install on any Red Hat Linux"

Tested on :

Host : Lubuntu 18.04 x64
Guest : Oracle Linux 5.7 ( fresh installation )
