Greetings, Per my previous email, I'm trying to setup the release process for Numpy on my MacBook Pro. When trying to build Numpy 1.4.1r3 with Python 2.5.4 I get a broken toolchain error (below). I do not get this error when trying to build Numpy with Python 2.6.5 - and there is nothing fundamentally different (that I know of) between my Python 2.5.4 and Python 2.6.5 environments. To address a previous suggestion I received offline, I do have sufficient permissions (I've even tried using sudo, just to make sure) and I do have setuptools installed. Any help, would be appreciated.
