postscript viewer that can "measure" distances?

gsview is a postscript viewer that has the capability of showing
distances (in mm or points etc.) in a ps-file. (Click on two points in
your file and it will report their distance).

Is there something with similar capabilities in Debian? I couldn't find
out how to use gv or kghostview to accomplish that and GSview [1] is not
in debian [2].

Thanks,
