Perhaps you'll need to compile more with guile-3.0-latest. If it's not
too much I suppose you could try moving guile-3.0-latest to guile-3.0.
Otherwise I guess you'll need to find where <file-system> is being
compiled and replace that guile-3.0 with guile-3.0-latest too, and then
see where the next failure is.
