Doh, you're right. The commit was from June 2012, not June 2013! So
indeed 2013.05 already pointed to 7.10.3. Sorry for the confusion :-(

So indeed, there's something wrong going on with how the mirror is
updated. We've had 7.10.3 since almost a year and it's not in our
mirror.

I don't think we ever did that for Mesa.

Note that Spenser Gilliland is currently reworking the Mesa package
quite significantly. In the recently posted "[Buildroot] [PATCH 4/6]
mesa3d: reorganize, modularize, and bump to version 9.1.6", he bumped
Mesa to a recent version.

Can you cook a patch for mesa3d.mk to fix this for the 2013.08 release
(since Spenser patch will not be part of 2013.08) ?

Thanks!
