Research direction

Start with the MacPorts-Python installation instructions and reproduce sudo port install py27-wxpython, then test import wx with the Python commands shown on Snow Leopard. Compare the architectures of Python and wx/_core_.so; done means identifying a supported installation or updating the instructions to explain the working invocation.

Written by the indexing model from the issue text.

Description

After following the instructions at http://astrofrog.github.com/macports-python/ then I installed wxpython with:

sudo port install py27-wxpython

This command succeeded but did not result in an importable wx package:

mac% pythonw
Python 2.7.2 (default, Mar  5 2012, 17:39:56) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin

>>> import wx
Traceback (most recent call last):

    import _core_
ImportError: dlopen(/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/wx-2.8-mac-unicode/wx/_core_.so, 2): no suitable image found.  Did find:
    /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/wx-2.8-mac-unicode/wx/_core_.so: mach-o, but wrong architecture

I think this is the same as this thread:

http://mail.python.org/pipermail/baypiggies/2011-January/007356.html

I'm currently trying the suggested fix:

$ port upgrade --force --enforce-variants  \
   py27-wxpython python27 +universal

The above fix did not change the error.

What works is

$ arch -i386 /opt/local/bin/python2.7 -c 'import wx'
