Mesa at v21 removed the software OSMesa driver (see 
https://www.phoronix.com/scan.php?page=news_item&px=Classic-OSMesa-Retires ). 
We were already using the gallium driver so I think there is no change for us, 
but the compile flag changed to a boolean: true for what was before gallium, 
based on my reading of the change 
https://cgit.freedesktop.org/mesa/mesa/commit/?id=ee802372180a2b4460cc7abb53438e45c6b6f1e4

Will do, sorry about that (I think I did do that but may have manually altered 
the header).

By the way, I'm looking now and see mesa-opencl failing, I'll take a look 
(perhaps an option change or library location?).
