转载：Quick way to reinstall dependencies with --universal

brew中，wine要求它所依赖的libpng带有 -- universal选项，而默认情况下10.8的苹果系统里的libpng是不带这个选项的。解决方法就是先 brew rm libpng 再 brew install libpng -- universal .其它依赖项，同理。 --universal是什么东西？不明觉厉。

亮点：

When trying to install wine (for example), it requires some of its dependencies to be installed with the --universal flag:

$ brew install wine

Error: wine dependency jpeg not installed with:

--universal

The workaround for this is to remove and install each dependency separately:

$ brew remove jpeg

Uninstalling /usr/local/Cellar/jpeg/8d...

$ brew install --universal jpeg
