For all I know, saying "bindist" affects installation location is totally
incorrect.

It's also not proprietary code. It is all FOSS code, but some algorithms are
patented in some countries, and in some countries those patents might even be
valid, so if you were not building Mesa only for yourself, you might maybe
perhaps one day get into trouble if you have enough money to be stolen.
Whatever, I don't really understand the legal matters, but I believe it depends
on your country a lot.

I repeat: it is not proprietary. Patent-encumbered is a different thing.

Whether you have "bindist" or not makes no difference to Weston. If you have
"bindist" and see some applications not working, then you could consider
disabling it. It only affects some GL extensions whether they work or not.
Weston uses none of that.

"bindist" is a short for "it is safe to redistribute the binaries built from
this package in all countries".

No, you should not need to do any symlinking manually. 'eselect' should do all
that, and reinstalling Mesa should trigger it automatically.

weston-keyboard is an on-screen keyboard program intended primarily for
touchscreens when you don't have a real keyboard.

If it's really missing, it's an issue in the Gentoo packaging or the Weston USE
flags you used.

Cool, no worries.
