The compiling requirements are not complete, missing are - TransFig/fig2dev from xfig homepage - dvipdf (where to find that btw..?) The last one, dvipdf can be replaced by "dvipdfm", which is part of teTex-3.0 which is anyway needed by only changing one line in Makefile: dvbapi.pdf: dvbapi.dvi - dvipdf $< $@ + dvipdfm -o $@ $< Regards, Winfried
