I'm having trouble building mesa to support native steam on fedora 18 linux

system is:
Linux localhost.localdomain 3.6.9-4.fc18.x86_64 #1 SMP Tue Dec 4
14:12:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

I have native intel graphics:

00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960
Integrated Graphics Controller (primary) (rev 0c)
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960
Integrated Graphics Controller (secondary) (rev 0c)

I've read on intel's site that the newest drivers should support OpenGL
3.1 on that hardware, and that I need a recent mesa.

So I got mesa down via git and configured it as:

./configure --with-driver=dri --enable-gles1 --enable-gles2
--enable-texture-float

But it decides that it's a 2.1 rather than 3.1 system:

version: 2.1 Mesa 9.1-devel (git-bd87441)

Checking to see why I found that I have:

ctx->Const.GLSLVersion: 120 but need >=130 for 3.0 and >=140 for 3.1
ctx->Extensions.EXT_transform_feedback: 0 needed for 3.0 or higher but
not true
ctx->Extensions.ARB_texture_buffer_object: 0 needed for 3.1 or higher
but not true
ctx->Extensions.ARB_uniform_buffer_object: 0 needed for 3.1 or higher
but not true

Should I be able to get this working on this hardware?  Is it a
configuration problem?  I'd love to play steam games on this machine
without using wine.
