GCC error when installing MySQL_python 1.2.2 (Mac

I'm trying to install MySQL_python 1.2.2 (I specifically need this version, not the current 1.2.3) on Snow Leopard, and getting this error below.

Command to install:

pip install -Iv http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.2/MySQL-python-1.2.2.tar.gz/download

And a portion of the trace:

Has anyone seen this error before?

回答1:

A quick google search yielded this answer:

To get mysqldb working on leopard I found I had to edit _mysql.c and edit out the lines:
#ifndef uint
#define uint unsigned int
#endif     
I also had to edit site.cfg and mark threadsafe to False.

After doing this, I managed to get MySQLdb to install, great! Not so fast, there was yet another problem:

Referenced from: .../_mysql.so Reason: image not found

The solution:
sudo ln -s /usr/local/mysql/lib/ /usr/local/mysql/lib/mysql

回答2:

As the error says, things have been redefined. I've gotten around this in the past by commenting out the offending declarations in the source of the library being build. That solution however has some obvious problems...
