No, I was just thinking you might be able to pick out the bit you need.
It looks like the relevant bit is

 \markup 
     { \postscript #"
                    gsave
                    initmatrix
                    1 setlinewidth 40 40 moveto 517 0 rlineto 0 760
rlineto -517 0 rlineto 0 -760 rlineto  stroke
                    0.5 setlinewidth 45 45 moveto 507 0 rlineto 0 750
rlineto -507 0 rlineto 0 -750 rlineto  stroke
                    grestore" }

That is, you can make a markup that draws (in this case two) boxes
around the page independently of the music on the page, using
postscript. That compiles on 2.19.43 I see.
