Comment (by mojca@…):

 I see one more "problem" with the following:
 {{{
 depends_build-append    bin:pdflatex:texlive-latex \
                         bin:gs:ghostscript \
                         port:texlive-latex-extra
 }}}
 This doesn't make any sense. The whole point of `bin:pdflatex` is to allow
 using external TeX Live. However `port:texlive-latex-extra` depends on
 `texlive-latex`, so one ends up installing `texlive-latex` no matter what.
 Plus, if external TeX distribution doesn't provide packages required for
 doxygen, texlive-latex-extra is of no help anyway. External pdflatex won't
 see the files from texlive-latex-extra unless configured to search there.

 Either change that to
 {{{
 depends_build-append    bin:pdflatex:texlive-latex-extra \
                         bin:gs:ghostscript
 }}}
 and assume that external latex works sufficiently well, or require the one
 from MP from the start:
 {{{
 depends_build-append    port:texlive-latex-extra \
                         bin:gs:ghostscript
 }}}
