Why would you need multiple directories in TEXMFDIST since it is GUIX_TEXMF job
to collect them in a single place ?

I can’t find the patch you’re pointing to, but I think it is a mistake to add
GUIX_TEXMF in Gnuplot in the first place.

In HEAD, this file is not found because Gnuplot installs the file in the wrong
place :
(string-append "--with-texdir=" #$output
"/texmf-local/tex/latex/gnuplot")
should be
(string-append "--with-texdir=" #$output
"/texmf-dist/tex/latex/gnuplot")
