Blender 2.59 crashes on startup - Mac 32 bit

I am on a MacBook Pro running Snow Leopard, 10.6.8

2.53 GHz Intel Core 2 Duo, 4 GB ram, NVIDIA GeForce 9600 GT, 256 VRAM

2.58a and previous have all run fine. No joy with 2.59.

Any suggestions welcome.

Thank you.

Crashes on my iMac as well, not only in 32 bit but all builds directly from the Blender website. Bummer really!

2.93GHz Core I7; 12 GB memory; ATI HD 5790M; OSX 10.6.8)

I tried to find another 2.59 version at Graphicall, but the experimental with the Tiles patch, while it worked, would not let me do add-ons and gave me errors.
