$PWD/lib? > 2. Move the make xdemos line to after ninja install of the main package. Simpler (as you and Thomas seem to think too)? Actually, it prevents the demos from being linked to an older library. But you know I do not like having two packages on the same page :), unless both can be merged, which means installing everything at the same time. > > The issue is that testing would require a complete reinstall of xorg. > > I suppose I could just rename /opt/xorg to /opt/xorg.save and rebuild just > xorg thru mesa and then restore the original by removing the new partial xorg > and renaming back.

Agreed. I can do that with porg (rather than jhalfs): exit Xorg, porg -r mesa, then try to build, using the script jhalfs generated, after adequate modification. I think I'll try a sed to the demos Makefile...
