Almost, groff and grops can find the SS file, which gives the widths of the SS 
glyphs, but grops cannot find the Symbolsl.pfa file because it is not listed 
in the download file it finds.

After the greek characters comes the horizontal line between 1/2. If the move 
to the start of the line before drawing is a relative movement from the end of 
greek characters then it will be in the wrong position.
