[gentoo-user] serious problems trying to go to new abi_x86_32 support

[covici@ccs.covici.com]

Hi.  So, I am trying to go to the new support for abi_x86_32, so I
unmerged all the emul_x86 packages (after doing quickpkg on them,
because I am a coward), and then it was complaining that I should run
emerge @preserved-rebuild which I did and every time I run that, it
gives me another package to change its use flag to add abi_x86_32.
After doing some 70 of those (a pain), I get to something which I cannot
solve.  At some early point portage suggested that I run --newuse
--update when doing this, but now I am down to the following:
!!! All ebuilds that could satisfy
">=sys-apps/systemd-212-r5:0/2[abi_x86_32(-)?,abi_x86_64(-)?,abi_x86_x32(-)?,abi_mips_n32(-)?,abi_mips_n64(-)?,abi_mips_o32(-)?,abi_ppc_32(-)?,abi_ppc_64(-)?,abi_s390_32(-)?,abi_s390_64(-)?]"
have been masked.
!!! One of the following masked packages is required to complete your
request:
- sys-apps/systemd-9999::gentoo (masked by: package.mask, missing
keyword)
/etc/portage/package.mask:
#need that system because of older kernel

- sys-apps/systemd-219-r2::gentoo (masked by: package.mask)
- sys-apps/systemd-218-r3::gentoo (masked by: package.mask)
- sys-apps/systemd-216-r4::gentoo (masked by: package.mask)
- sys-apps/systemd-216-r3::gentoo (masked by: package.mask)
- sys-apps/systemd-215-r3::gentoo (masked by: package.mask)

(dependency required by "virtual/libudev-215-r1::gentoo" [ebuild])
(dependency required by "media-libs/mesa-10.3.7-r1::gentoo[udev]"
[ebuild])
(dependency required by "x11-libs/cairo-1.14.2::gentoo[opengl]"
[ebuild])
(dependency required by "media-libs/harfbuzz-0.9.40::gentoo[cairo]"
[ebuild])
(dependency required by "x11-libs/pango-1.36.8::gentoo" [ebuild])
(dependency required by "x11-libs/gtk+-2.24.27-r1::gentoo" [ebuild])
(dependency required by "www-plugins/nspluginwrapper-1.4.4-r3::gentoo"
[ebuild])
(dependency required by "@preserved-rebuild" [argument])

If I delete the --update, I just get 
Calculating dependencies  ... done!

So, how can I fix this mess?

Thanks in advance for any ideas.
