Thanks Mauro and Hans for your fast help, its a good starting point for 
updates.
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 $@ $<
