Re: [NTG-context] Minimals and dvipng

3. export TEXFONTMAPS=/path/to/texlive/texmf-var/fonts/map/dvips

Did I write fonts/map/dvips? It should have been fonts/map/dvips/updmap (or, alternatively, fonts/map/dvips// with the trailing double slash). And it seems to work without copying the dvipng binary, and with setuptex as well. Of course your mileage may vary, but anyway, the key is setting TEXFONTMAPS. Arthur
