Your glxinfo output is from two different graphics cards. Your "working" copy was using:
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: AMD Radeon HD 6970M OpenGL Engine
OpenGL version string: 2.1 ATI-7.18.18
Your "failing" copy was using:
OpenGL vendor string: Intel Inc.
OpenGL renderer string: Intel HD Graphics 3000 OpenGL Engine
OpenGL version string: 2.1 APPLE-7.32.12
