Apart from moving to the latest upstream I think the singular spkg is due for a spring clean. It build an enormous amount of targets in a way that looks like a very careful choreography and apart from libsingular and the singular binary there is no indication sage uses any of the other stuff built.
I have just read William's opinion and it may be true that is generally easy to build. But reproducing the set up used in the sage spkg from a packaging point of view is quite difficult.
