ham/gnuradio-doxygen: DEPENDS vs BUILD_DEPENDS

["Darrin B. Jewell" <dbj%netbsd.org@localhost>]

I recently built gnuradio and gnuradio-doxygen failed because
it didn't generate some .png files for formulas.  Reviewing the
logs showed that it failed to find dvips and adding this line
fixed it:

  BUILD_DEPENDS+=       dvipsk-[0-9]*:../../print/dvipsk

I would commit that change, except that I notice that it has
full DEPENDS lines for these:

  DEPENDS+=     web2c-[0-9]*:../../print/web2c
  DEPENDS+=     texlive-collection-latex-[0-9]*:../../meta-pkgs/texlive-collection-latex

I'm wondering why those are DEPENDS and not BUILD_DEPENDS ?

Does it need tex installed at run time instead of just build time?
Everything that package installs is in share/doc.
