Blender 2.57b crashes immediately

Hi

I can’t get Blender 2.57b to open on my PPC Mac running OSX 10.4.11

Whenever I try it just crashes immediately.

I checked for a crash report in the console application and it mentions this:

dyld: Library not loaded: /usr/lib/libiconv.2.dylib
Referenced from: /Applications/blender-2.57b-OSX_10.5_ppc/blender.app/Contents/MacOS/blender
Reason: Incompatible library version: blender requires version 7.0.0 or later, but libiconv.2.dylib provides version 5.0.0

I assume this is the problem, only I don’t know how to remedy it. Could anyone offer some guidance?

Thank you
