It is Metaobj's fault, it redefines (and therefore blocks access to)
the primitive command arctime. So I guess you should complain to
Denis Roegel (at the very least he should save the primitive arctime
under a different name). A workaround (I think) is this:

   input metaobj;
   primarydef pct along pat =
     arctime (pct,pat) of pat
   enddef ;
