Maybe that's just my local problem: I was taking those packages from a
Debian unstable build and running them on a Trisquel aramo machine.
Still, if there is some common magic that Debian Guile packages could do
to improve things, I want to learn.  Build them using an old Guile
perhaps?  Assuming object files built by 3.0.7 work fine with 3.0.9.

Btw, is there a Debian Guile packaging wiki page or group?  I looked at
a couple of different guile packages in Debian and they all seem to do
some similar things wrt dwz, shlibs, etc; having this documented
somewhere would have helped me.
