我遇到了与I'm trying to install psycopg2 onto Mac OS 10.6.3; it claims it can't find "stdarg.h" but I can see it's there; what should I do?非常类似的问题（除了我在OS X 10.7和PostgreSQL v 9.0.5上），我正在考虑更改我的psql配置c编译器。
当我在终端输入pg_config时，我得到：
BINDIR = /usr/bin

INCLUDEDIR = /usr/include

VERSION = PostgreSQL 9.0.5
我想知道如何更改pg_config（所以我可以设置CC = gcc-4.2）或类似的东西。

pg_config只是一个提供信息的工具，它不是典型意义上的“配置”，您可以编辑属性。如果要更改pg_config提供的值，则需要在util之外手动执行此操作（在您的情况下，您需要安装新的C编译器）。
