Firstly, this error shouldn't have occurred because our source mirror has this 
file:

  http://downloads.yoctoproject.org/mirror/sources/mesa-10.6.3.tar.xz

I'm unsure as to why that wouldn't have worked unless your configuration 
clears out the default value of MIRRORS, or our source mirror couldn't be 
accessed by you for some reason. mesa-gl's log.do_fetch (path shown in your 
error log) would explain exactly which URLs it tried if you did want to figure 
that out.

Secondly, regarding copying the file into the downloads directory, that alone 
isn't enough, you also have to touch a ".done" file next to the file in the 
downloads directory (the name of the file with .done appended to it) so that 
it assumes the file completely downloaded.

Thirdly, you are using what is by now quite an old version of the build system 
- and you're building for rasperrypi2 which isn't the board you say you have 
(rasperrypi3) - perhaps because the raspberrypi3 configuration isn't available 
in that version, not sure. Maybe someone else can chime in regarding the 
camera software for newer versions, I'm not sure about that either.

Cheers,
Paul
