That sounds annoying :(

I recommend updating all the packages that are trying to propagate
r-mass. That is, R, r-car, and r-caret. We recently made a change to
throw an error here:

https://bugs.gnu.org/27271

I don't fully understand the impact of the change so I asked Ludovic to
chime in.

Guix is a build-from-source distro that can offer pre-built binary
substitutes as a side-effect of the functional package management model.
Your request has been discussed previously but, AFAIK, it's not being
worked on at the moment.

We are currently bringing some more x86_64 / i686 build machines online,
so the build / substitute ratio should improve soon. We know it should
be better.
