当我跑酿造医生我去警告的负荷。 所以我说干就干，清理现有的安装，从头做到了。
现在，我仍然得到一些警告：
Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.
Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:
/opt/sm/pkg/active/bin/curl-config
/opt/sm/pkg/active/bin/ncurses5-config
/opt/sm/pkg/active/bin/ncursesw5-config
/opt/sm/pkg/active/bin/pkg-config
/opt/sm/pkg/active/bin/xml2-config
/opt/sm/pkg/active/bin/xslt-config
Warning: You have a non-Homebrew 'pkg-config' in your PATH:
/opt/sm/pkg/active/bin/pkg-config
`./configure` may have problems finding brew-installed packages using
this other pkg-config.
但由于我只使用OS X前几天开始，我不知道，如果提到的配置文件是相关的，或者如果我可以删除它们？ 已经在寻找通过论坛几个小时，但仍然没有在此刻更明智...任何意见非常感谢！
