在Mac OS 10.6上安装psycopg2时出错

Question

Hi i am trying to install psycopg2 on Mac 10.6. After i install i get this error when i try to import

import psycopg2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Library/Python/2.6/site-packages/psycopg2/__init__.py", line 69, in <module>
from psycopg2._psycopg import BINARY, NUMBER, STRING, DATETIME, ROWID
ImportError: dlopen(/Library/Python/2.6/site-packages/psycopg2/_psycopg.so, 2): Symbol  not found: _PQbackendPID
Referenced from: /Library/Python/2.6/site-packages/psycopg2/_psycopg.so
Expected in: flat namespace
in /Library/Python/2.6/site-packages/psycopg2/_psycopg.so

I got the source from http://initd.org/psycopg/download/ and tried to build from source using setup/easy_install with the value for pg_config set to /Library/PostgreSQL/8.4/bin/pg_config in setup.cfg

I tried all these alternatives and nothing seems to work

根据这个链接 ，psycopg2似乎必须在MacOSX上以32位模式工作
