%changelog
* Tue Nov 2 2005 Mike A. Harris <mharris@redhat.com> 6.4-2
- Added mesa-6.4-multilib-fix.patch to instrument and attempt to fix Mesa
  bin/installmesa script to work properly with multilib lib64 architectures.
- Set and export LIB_DIR and INCLUDE_DIR in spec file 'install' section,
  and invoke our modified bin/installmesa directly instead of using
  "make install".
- Remove "include/GL/uglglutshapes.h", as it uses the GLUT license, and seems
  like an extraneous file anyway.

* Thu Oct 27 2005 Mike A. Harris <mharris@redhat.com> 6.4-1
- Updated to new upstream MesaLib-6.4
- Updated libGLU.so.1.3.060400 entry in file manifest
- Updated "BuildRequires: libdrm-devel >= 1.0.5" to pick up fixes for the
  unichrome driver.

* Tue Sep 13 2005 Mike A. Harris <mharris@redhat.com> 6.3.2-6
- Fix redhat-mesa-driver-install and spec file to work right on multilib
  systems.
  
* Mon Sep 5 2005 Mike A. Harris <mharris@redhat.com> 6.3.2-5
- Fix mesa-libGL-devel to depend on mesa-libGL instead of mesa-libGLU.
- Added virtual "Provides: libGL..." entries for each subpackage as relevant.

* Mon Sep 5 2005 Mike A. Harris <mharris@redhat.com> 6.3.2-4
- Added the mesa-source subpackage, which contains part of the Mesa source
  code needed by other packages such as the X server to build stuff.

* Mon Sep 5 2005 Mike A. Harris <mharris@redhat.com> 6.3.2-3
- Added Conflicts/Obsoletes lines to all of the subpackages to make upgrades
  from previous OS releases, and piecemeal upgrades work as nicely as
  possible.

* Mon Sep 5 2005 Mike A. Harris <mharris@redhat.com> 6.3.2-2
- Wrote redhat-mesa-target script to simplify mesa build target selection.
- Wrote redhat-mesa-driver-install to install the DRI drivers and simplify
  per-arch conditionalization, etc.

* Sun Sep 4 2005 Mike A. Harris <mharris@redhat.com> 6.3.2-1
- Initial build.
