Not sure what or where bootstrap is.
I built from Fedora 24 src.rpm, so I am assuming from what you say that I  
have to rebuild Octave, which seems a bit at odds with the text describing  
the workaround, as it only talks about a patch to the image package on  
Octave Forge.
Can someone please clarify exactly what needs to be done?
