The report that I promised. Allow me not to have to rephrase what I had
prepared before sending my post immediately previous to this post.

The reinstalls/installs are not done, there's likely some two hours for only
libreoffice to compile, and that one is last to compile and install, but...

[But] I have installed Inkscape, dear colleage!

# inkscape -V
Inkscape 0.91 r13725 (Sep 20 2016)
#

So, the previously written text follows below.

Wait a minute, maybe inkscape can be installed. I do have poppler installed in
my machines:

# equery l poppler
* Searching for poppler ...
[I--] [??] app-text/poppler-0.32.0:0/51
g0n ~
#

The thing is, Inkscape only needs a newer one.

After I commented out what hopefully is not necessary (and I don't remember
why it was there):

> grep poppler /etc/portage/package.mask

#>=app-text/poppler-0.34.0

(which said to preclude versions greater than 0.34.0)

And allowed emerge to change my /etc/portage/package.use which previously had
this entry:

app-text/poppler qt4

and I allowed the emerge to change it along these diff lines:

+# required by media-gfx/inkscape-0.91-r3::gentoo
+# required by inkscape (argument)
+>=app-text/poppler-0.47.0 cairo
lines 1-10/10 (END)

All that is now in effect equivalent to this setup:

>=app-text/poppler-0.47.0 qt4 cairo


I believe.

Let me see what happens. I'd be excited to be able to install Inkscape, and
then likely it can be installed on a sans-dbus Devuan as well.

( I see now I also need to install cairo... Hmmmhh... )

Let me see:

# emerge -tuDNf inkscape


These are the packages that would be fetched, in order:

Or will I be able to install Inkscape? Has Cups gone dbus-dependent? Because
that seems to be the issue:

This it is like currently:
# 2 ln were temporarily masked. Else wouldn't have 'emerge world'.
>=net-print/cups-filters-1.0.73
>=net-print/cups-2.0.4

#>=app-text/poppler-0.34.0

Turning it to all commented out, and trying now...

Have a look! This means you can very like have sans-dbus Inkscape in your
Devuan too!

And here I went installing. (and if I don't report issues with
installing any of the above that are being installed, than it went all
fine)

Again, this means that the trail has been blazed and that it can be done in
Devuan as well. If only I were really a developer ;-) ...
