Agreed. That is why it is an _option_ now.

The reliance on pdflib is also an option. But I would agree with you that it
should be off by default, instead of on. I seem to recall that the pdflib
output didn't really work when I tried it, so I dropped it.

So you would advocate to set all options to off be default? Why not submit a
PR to that effect?

Looking at the port Makefile version 1.75 (maxima 5.26.0_1), there is no TeX
dependency.

And who is to say what is "appropriate", other than the respective maintainers
of the port in question? In my opinion, packages are a dead-end street. They
might be convenient but they are also "one size fits all". Which as your
message demonstrates is not the case. :-)
Your post got me thinking, so I checked which terminals are available in a
gnuplot that only includes the options X11, GD and CAIRO:
canvas cgm corel dpu414
dumb dxf eepic emf
emtex epslatex epson_180dpi epson_60dpi
epson_lx800 fig gif gpic
hp2623a hp2648 hp500c hpdj
hpgl hpljii hppj imagen
jpeg latex mf mif
mp nec_cp6 okidata pbm
pcl5 pdfcairo png pngcairo
pop postscript pslatex pstex
pstricks push qms regis
starc svg tandy_60dpi tek40xx
tek410x texdraw tgif tkcanvas
tpic vttek x11 xlib
xterm
It seems that PDF (via cairo) and SVG are supported in this case. I haven't
tested SVG, but pdfcairo seems to work OK.
