bug#64827: Texlive-biber not installable

[Andreas Enge <andreas@enge.fr>]

Hello,

the latest texlive update (cudos!) has left texlive-biber broken, at least
in conjunction with the monolithic texlive:

$ guix shell texlive texlive-biber
The following derivation will be built:
  /gnu/store/b2dzc8ayda5dp53s5dq40v0f41290b4c-profile.drv

building CA certificate bundle...
listing Emacs sub-directories...
building fonts directory...
building directory of Info manuals...
