You can check out pkgsrc 2023Q1 (assuming that's the binary packages you
are using which are built for 10) and build just that package from
source.  It is ok to mix source/binary.  What is not ok is to mix
architecture, OS version, or branch.  (Well, you can do what you want
given the license, but not ok means I expect trouble!).

Does gdk-pixbuf2 load the rsvg library dynamically, or is it linked in
at configure time?

Is this documented by gdk-pixbuf2?

Does gdk-pixbuf2 already depend on rust?  If not, this will result it in
not being available -- and a whole slew of depending packges -- not
being available on many platforms.  Or, it could drag in unmaintained
libsrvg-c, which would be a security problem.

Very likely gdk-pixbuf2 should have a rsvg option, and that perhaps
should be default on if the platform has rust.

If you want to work on this, then besides consensus on the above
suggestion/guess, staging a package with this feature in wip would be
the way to make progress.

Perhaps my messages will provoke others, too...
