Comment(by eborisch@…):

 But the docs variant is to build doxygen's documentation; the variant
 description and name don't provide the user any indication that without it
 Doxygen will be unable to create pdf (via latex output) documentation.
 Someone familiar with doxygen may only want the output support, but not
 wait for the actual documentation to be re-created locally.

 Perhaps something like this:
 {{{
 variant docs description {Include the doxygen PDF documentation and LaTeX}
 requires {latex} {
   build.target-append pdf
   use_parallel_build  no
 }

 variant latex description {Support latex/PDF Doxygen output} {
   destroot.target-append  install_docs
   depends_build-append  bin:pdflatex:texlive \
         bin:gs:ghostscript \
         port:texlive-latex-extra
 }
 }}}
