I think you are right. I then tried manually updating some packages with 
"make replace"... and I got a hang also when building glib2.
So pkg_rolling-replacing is just on top and has nothing to do with it.


The place and file where the hang occours is consistent.

In my case, libvdpau is not using cmake! you can see on the command line 
 CMAKE=false

It is involving make, python and meson:
