What about this (you need groff's -U switch, of course):

  .de PSx
  .  open PS-file PS.in
  .  de pic-contents PEx
  ..
  .
  .de PEx
  .  write PS-file .PS
  .  writem PS-file pic-contents
  .  write PS-file .PE
  .  close PS-file
  .  sy pic PS.in > PS.out
  .  if \\n[systat] \
  .    ab Error in calling pic (line \\n[.c])
  .  so PS.out
  ..
  .
  .ds text foo
  .
  .PSx
    box width 0.6 "\*[text]"
  .PEx
