Comment (by mojca@…):

 Clemens, I had exactly the same brilliant idea until someone reminded me
 that once you install `texlive-latex`, `bin:pdflatex:texlive-latex-extra`
 will be automatically satisfied with `texlive-latex`, so no `texlive-
 latex-extra` would be pulled in.

 Peter, I'm sorry, I was referring to a different "case 2". I thought we
 were talking about the following (which is "case 1" in your list):
 > * '''external''' pdflatex without sufficient packages installed: then
 the package texlive-latex-extra is useless, external pdflatex cannot see
 the files installed by texlive-latex-extra anyway
 But I see now that you were referring to:
 > 2. If we find a pdftex and it is provided by MacPorts, we would like to
 ensure that a minimal set of ports (see above) is also installed;
 Yes, that is exactly the "problematic" case that we need to solve
 properly.
