 Replying to [ticket:47972 mojca@…]:

 +texlive` functional (possibly defining different `depends_build` and
 `depends_run`)

 Aha! I hadn't realized that MacPorts had adopted the many-small-packages
 approach.
 LaTeXML doesn't actually *require* any tex, but will work best with at
 least a minimal
 amount.  You'd likely want latex, mktexlsr, dvips, and can use dvipng,
 dvisvgm.
 Can use other packages if they're installed, but the user can install
 whatever they
 expect to use.

 I would guess "texlive-latex" is sufficient.

 > * calling `system /usr/texbin/mktexlsr` might be problematic (the files
 from MacTeX might be owned by `root`)

 That's true. Does it fail or warn in such circumstances?
 What will happen is that MacTeX's latex won't be able to find LaTeXML's
 style files,
 unless the user re-runs mktexlsr with appropriate permissions.

 > * one might want to disable calling `mktexlsr` during `make install`

 Could be; Is it better to run from "make" or from "post-activate"?
 OR, does the PortGroup texlive automatically arrange for mktexlsr?

 > * I can imagine that `depends_build` might not even need to depend on
 anything from TeX Live even with `+texlive` variant: all the package needs
 to do is to copy two files to the appropriate place (or am I wrong?).

 Other than mktexlsr (so the files are findable by TeX), that's right.
