Hi Anders,

Thank you for the detailed review and analysis. It helped.

Yes it is wrong ...

https://git.rtems.org/rtems-source-builder/tree/bare/config/devel/qemu-git-1.cfg#n24

It has been wrong a long time.

That is a bug in bare/config/bare-config.cfg. It needs to use the same 
logic as the rtems/config/rtems-version.cfg or jus include that file. I 
have raised a ticket.

Thanks for spotting this. It looks like the release source capture is 
not picking up this package. The glib-2.48.2.tar.xz maybe coming from 
the devel/qemu-couverture. The devel/qemu4 is not in the list.

https://git.rtems.org/rtems-release/tree/rtems-source-packages#n32

I need to review this file and fix the list. I have added ticket #3967. 
It looks like devel/qemu is under 4.11 for some historical reason.
