PyRosetta 2.0 is build on Mac OS X with standard GCC shipped by Apple. (See full version signature below) So you should be able to run it if you have not alter your system. ie using default 64 bit python etc. Which version of Mac OS have you tried? And with version of python?

$ gcc -v
Target: i686-apple-darwin10
Configured with: /var/tmp/gcc/gcc-5664~89/src/configure –disable-checking –enable-werror –prefix=/usr –mandir=/share/man –enable-languages=c,objc,c++,obj-c++ –program-transform-name=/^[cg][^.-]*$/s/$/-4.2/ –with-slibdir=/usr/lib –build=i686-apple-darwin10 –program-prefix=i686-apple-darwin10- –host=x86_64-apple-darwin10 –target=i686-apple-darwin10 –with-gxx-include-dir=/include/c++/4.2.1
Thread model: posix
gcc version 4.2.1 (Apple Inc. build 5664)

Qulprit: Witch version of OS X do you use? You need to have 10.6 to run this build. (Since you saying that your python is 2.5 I am suspecting that its OS X 10.5). If you do have 10.6 and just have python2.5 as your default try this: execute python2.6 directly ie: /usr/bin/python2.6

Here is my configuration:

gcc -v
Using built-in specs.

Luca, are you running on a 32-bit only Mac? There are a few Intel Mac models that only had Core Duo CPUs, and I’ve seen that error when they try to run 64-bit executables.

Run:

sysctl hw.optional.x86_64


On 64-bit capable machines, it prints 1. On 32-bit only machines, it prints 0.
