Installed texlive-bin and texlive-base with fairly new guix:
$ guix --version
guix (GNU Guix) 9d58e8819fdbc4c1c8a1ef6149e2d2376731a6a6
But I stil cannot export to PDF via Emacs:

This is pdfTeX, Version 3.14159265-2.6-1.40.19 (TeX Live 2018)
(preloaded format=pdflatex)
 restricted \write18 enabled.
