我已经和作者联系了多次，问题讨论

我咨询了一些使用Mac的开发人员，说是我的Xcode是最新版本，然后我安装了Xcode4.1，安装依旧失败，后来使用GCC-10.7-v2.pkg这个软件包，安装还是失败。
OS: Mac OS X Lion 10.7.3
gcc: llvm 4.2
g++: llvm 4.2
node: 0.6.17
npm: 1.1.21
mysql: 5.5.21
node是用git clone源码安装的，mysql是dmg安装包安装的，已经配置环境变量。

localhost:nodejs yangzhaojie$ CXX=/usr/bin/gcc npm install mysql-libmysqlclient
npm http GET https://registry.npmjs.org/mysql-libmysqlclient
npm http 200 https://registry.npmjs.org/mysql-libmysqlclient
npm http GET https://registry.npmjs.org/mysql-libmysqlclient/-/mysql-libmysqlclient-1.3.2.tgz
npm http 200 https://registry.npmjs.org/mysql-libmysqlclient/-/mysql-libmysqlclient-1.3.2.tgz

> mysql-libmysqlclient[@1](/user/1).3.2 install /Users/yangzhaojie/tech/nodejs/node_modules/mysql-libmysqlclient
> node-gyp rebuild

info it worked if it ends with ok

设置CXX使用gcc和g++都是一样的，想问一下，有没有人遇到过同样的问题。高手们能知道这个错误怎么排除吗。
