Comment (by raimue at macports.org):

 I did a bad job, I did not really investigate what is going on. Actually
 it is looking for /opt/local/bin/tex and assumes texlive is installed if
 it is there. /opt/local/bin/tex is provided by texlive_base, but
 /opt/local/bin/pdflatex is provided by texlive. We have a problem here if
 texlive_base is installed but not texlive.

 I think there should be another dependency
 `path:${prefix}/bin/pdflatex:texlive`.

 Workaround: Install texlive before installing doxygen.
