Hi, not an experienced bug reported, but I am also experiencing this.  I wonder if the following attachment will help (it is the failed test build before portage tries to merge the package.)  Looks like something to do with the gentoo-sources Makefile not being in the expected place according to the package software.

[Comment 9 Goeran Bruns 2018-08-09 07:57:37 UTC]

Got this problem too.
 * Preparing vboxguest module
make -j2 HOSTCC=x86_64-pc-linux-gnu-gcc CROSS_COMPILE=x86_64-pc-linux-gnu- 'LDFLAGS=-m elf_x86_64' KERN_DIR=/usr/src/linux KERNOUT=/usr/src/linux all
/var/tmp/portage/app-emulation/virtualbox-guest-additions-5.2.14/work/vboxguest/Makefile.include.header:99: *** The variable KERN_DIR must be a kernel build folder and end with /build without a trailing slash, or KERN_VER must be set.  Stop.

Kernel layout is:
drwxr-xr-x 22 root root 4096 Apr 26 10:47 build-4.9.95-gentoo
lrwxrwxrwx  1 root root   19 Apr 26 10:34 linux -> build-4.9.95-gentoo
drwxr-xr-x 25 root root 4096 Apr 26 10:10 linux-4.9.95-gentoo

So build directory is separate from sources.

[Comment 10 Goeran Bruns 2018-08-13 09:53:38 UTC]

I looked into the problem.
In ebuild(/usr/portage/app-emulation/virtualbox-guest-additions/virtualbox-guest-additions-5.2.14.ebuild) in function pkg_setup var BUILD_PARAMS is set:

pkg_setup() {
        MODULE_NAMES="vboxguest(misc:${WORKDIR}/vboxguest:${WORKDIR}/vboxguest)
                vboxsf(misc:${WORKDIR}/vboxsf:${WORKDIR}/vboxsf)"
        use X && MODULE_NAMES+=" vboxvideo(misc:${WORKDIR}/vboxvideo::${WORKDIR}/vboxvideo)"

        linux-mod_pkg_setup
        BUILD_PARAMS="KERN_DIR=${KV_OUT_DIR} KERNOUT=${KV_OUT_DIR}"
        enewgroup vboxguest
        enewuser vboxguest -1 /bin/sh /dev/null vboxguest
        # automount Error: VBoxServiceAutoMountWorker: Group "vboxsf" does not exist
        enewgroup vboxsf
}

KERN_DIR is set to KV_OUT_DIR (see https://devmanual.gentoo.org/eclass-reference/linux-info.eclass/index.html for description).
Virtualbox requires it to be kernel build dir ending with build. (e.g. /lib/modules/4.9.95-gentoo/build) even so it is only a symlink.

As hotfix I changed the var via ebuild hook and it works.

#!/usr/bin/env bash
# /etc/portage/env/app-emulation/virtualbox-guest-additions-5.2.14

post_pkg_setup() {
        BUILD_PARAMS="KERN_DIR=/lib/modules/${KV_FULL}/build KERNOUT=${KV_OUT_DIR}"
}

[Comment 11 Travis Osterman 2018-10-04 17:20:41 UTC]

This is still a bug in 5.2.18

For anyone finding this, Goeran Bruns' solution worked perfectly.  Here are the exact steps

1. mkdir -p /etc/portage/env/app-emulation
2. nano -w /etc/portage/env/app-emulation/virtualbox-guest-additions
#!/usr/bin/env bash
# /etc/portage/env/app-emulation/virtualbox-guest-additions-5.2.14

post_pkg_setup() {
        BUILD_PARAMS="KERN_DIR=/lib/modules/${KV_FULL}/build KERNOUT=${KV_OUT_DIR}"
}
3. emerge --ask virtualbox-guest-additions

Yes, me too. The above workaround solved the build problem.
