I just built mesa with :

make clean
git pull origin
./autogen.sh --with-driver=xlib
gmake

And I agree from the output from --help this should be the same as make
linux-x86-64.

I tried a VTK test build against this mesa and I got this :

http://www.cdash.org/CDash/viewBuildError.php?buildid=606216

/home/kevin/mesa/lib/libOSMesa.so.7: undefined reference to
`_mesa_create_framebuffer'

This VTK is built with :

OPENGL_INCLUDE_DIR:PATH=/home/kevin/mesa/include/
OPENGL_gl_LIBRARY:FILEPATH=/home/kevin/mesa/lib/libGL.so
OPENGL_glu_LIBRARY:FILEPATH=/home/kevin/mesa/lib/libGLU.so
OPENGL_xmesa_INCLUDE_DIR:PATH=/home/kevin/mesa/include/
VTK_OPENGL_HAS_OSMESA:BOOL=ON
OSMESA_INCLUDE_DIR:PATH=/home/kevin/mesa/include/
OSMESA_LIBRARY:FILEPATH=/home/kevin/mesa/lib/libOSMesa.so

I really do not understand this missing symbol business since :

$ nm mesa/lib/libOSMesa.so | grep _mesa_free_context_data
                 U _mesa_free_context_data
$ nm mesa/lib/libGL.so | grep _mesa_free_context_data
0000000000078030 t _mesa_free_context_data

$ nm /opt/Mesa-7.8.1/lib64/libOSMesa.so | grep _mesa_free_context_data
                 U _mesa_free_context_data
$ nm /opt/Mesa-7.8.1/lib64/libGL.so | grep _mesa_free_context_data
0000000000092bc0 T _mesa_free_context_data

The symbol is defined in the same library in mesa built from the git
repo with autogen.sh --with-driver=xlib and in mesa built from the
release tarball with make linux-x86-64.

One VTK fails to build one VTK passes most tests :
