I can see the packages at
http://raspbian.raspberrypi.org/raspbian/pool/main/g/guile-1.8/
which correspond in version number to those that I had installed on
a jessie system (mine was i386) still being kept up-to-date as of
2019-03-28. I didn't use apt (obviously) to get to those packages,
but just browsed from http://raspbian.raspberrypi.org/raspbian
given on the page you referred to above.

So you could just download them by hand and install them with
either   dpkg -i foo.deb   (dependencies first) or with apt
and friends   apt install ./foo.deb
Note that to install .deb *files* with apt, the filename must
be a path starting with any of / or ./ or ../ else apt will
misinterpret it.

Watching conversations here, I think very hard, possibly involving
Python2→3 as well, though I might be wrong there. I don't think LP
would be using guile1 at all were it straightforward.

There does appear to be an open thread about compiling LP which
involves guile:
https://lists.gnu.org/archive/html/lilypond-user/2020-01/msg00319.html
and another about compiling libreadline into guile:
https://lists.gnu.org/archive/html/lilypond-user/2020-01/msg00198.html
which might be of help, but I've not tried any of this as I download
amd64 tarballs from the LP website myself.

Cheers,
David.
