If someone else runs into this: I found the reason and a workaround for
the issue described in my previous post. The problem bulding the docs
seems to be that the produced eps-files (voronoi.eps, triplot.eps, etc.)
have text entries of the form

  [ [({}) 200.0 0.0 true true 0 (0.2)]
  ] -66.7 MRshow

with a font '{}'. Debugging gs shows that gs can not find font '{}' and
then queries all system fonts. This action then consumes much resources.
This can be avoided by

  export GS_OPTIONS='-dNONATIVEFONTMAP -sSUBSTFONT=Helvetica'

which prevents using native fonts and replace all unknown fonts by
Helvetica.
