Description of issue

Not sure how to get rid of these warning when I run 'latexdiff':

latexdiff file.tex revised.tex > diff.tex

Can't exec "kpsewhich": No such file or directory at /opt/homebrew/bin/latexdiff line 1506.
Use of uninitialized value in string ne at /opt/homebrew/bin/latexdiff line 1506.
WARNING: listings package not detected. Disabling mark-up in verbatim environments

kpsewhich is part of texlive, once you installed it (brew install texlive), you would see the warning goes away

$ fd kpsewhich /opt/homebrew/Cellar/texlive
/opt/homebrew/Cellar/texlive/20240312_3/share/man/man1/kpsewhich.1
/opt/homebrew/Cellar/texlive/20240312_3/bin/kpsewhich

(the reason why we did not add texlive dependency is probably because of the CI burden of texlive formula, we could probably add a caveat on this)

Thank you so much, Chen. Works without any warnings now.
