OS X中pydev和外部库的问题

我已经成功地在我的Eclipse(3.5.1)中的OS X 10.6.3下安装了最新版本的pydev,并使用python 2.6.1
我在使我安装的库工作时遇到困难。
例如,我正在尝试使用cx_Oracle库,如果从用一些文本编辑器制作的简单脚本的python interpeter调用该库,它将非常有效。
但是我不能让它在Eclipse中工作:我有一小段代码:

import cx_Oracle
conn = cx_Oracle.connect(CONN_STRING)
sql = "select field from mytable"
cursor = conn.cursor()
cursor.execute(sql)
for row in cursor:
    field = row[0]
    print field

如果我从Eclipse执行它,我会得到以下错误:

import cx_Oracle
  File "build/bdist.macosx-10.6-universal/egg/cx_Oracle.py", line 7, in <module>
  File "build/bdist.macosx-10.6-universal/egg/cx_Oracle.py", line 6, in __bootstrap__
ImportError: dlopen(/Users/dave/.python-eggs/cx_Oracle-5.0.3-py2.6-macosx-10.6-universal.egg-tmp/cx_Oracle.so, 2): Library not loaded: /b/227/rdbms/lib/libclntsh.dylib.10.1

  Reason: no suitable image found.  Did find:
    /Users/dave/lib/libclntsh.dylib.10.1: mach-o, but wrong architecture

同一个代码段在Python外壳中非常有效

我在首选项--gt;pydev--gt;解释器--python中配置了eclipse中的interpeter,使用auto-config选项并选择找到的所有libs。

我在这里做错什么了?

编辑:启动

file /Users/dave/.python-eggs/cx_Oracle-5.0.3-py2.6-macosx-10.6-universal.egg-tmp/cx_Oracle.so

从命令行中可以看到:
