Hi Ken,


The only package we have that this seems to effect is 'asymptote'.

However, that only has a build-depends on libOSMesa-devel, it doesn't 
actually seem to depend on the run-time library.

(So I do wonder if there's some sort of problem in configuration or 
dependency generation here?)


I'm faced with a bit of a dependency knot, since the last version of 
libosmesa depends on a specific version of dri-drivers, which will 
prevent other mesa libraries being upgraded.

So it would be nice to know if asymptote is really using osmesa, in 
which case I'll have to work out how to keep it around, or if I can 
simply make the osmesa package obsolete.


There's no hurry about any of this, as I'm not planning on promoting 
this from test for a while.
