Well, Bob hasn't properly encapsulated his internal strings, macros,
and variables names into a macro-specific namespace; most notably, he
uses a string named `color' which is now used by groff itself.  But
this doesn't cause the problem.  Doing a quick test with

  groff -pet -ww -M. -mtrace -mm -mpresent demo.rof > demo.pps 2> demo.log

(replacing the smiley image with something different since it is
missing in the package) shows that there is a recursive call of the
address@hidden' macro which isn't changed in tmac.present.  J├Ârgen, can
you help here?  gpresent is available from

  www.science.uva.nl/~bobd/useful/gpresent/
