Hi Ricardo,

indeed, adding this package variation to the manifest fixed the issue for me:

---snip---
(define-public texlive-latex-base-fixed
  (package
    (inherit texlive-latex-base)
    (name "texlive-latex-base-fixed")
    (propagated-inputs (modify-inputs (package-propagated-inputs texlive-latex-base)
                                      (append texlive-babel)))))
---snap---

Looking at `guix refresh -l texlive-latex-base` a change like that would
be a world rebuild though. I tried adding something similar to
Guix’ tree, but there’s a loop somewhere I can’t figure out
(see attached patch). I’m guessing through texlive-build-system’s
#:texlive-latex-base.

Cheers,
Lars
