homebrew - Brew doctor gives out warnings

Question

when I ran brew doctor I go loads of warnings. So I went ahead, cleaned out the existing installation and did it from scratch.

Now I still get some warnings:

    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.

But since I only started using OS X a few days ago, I am not sure if the mentioned config files are relevant or if I can just delete them? Have already been looking through forums for hours, but still none the wiser at the moment... Any advice is very much appreciated!

Answer 1

Try taking /opt/sm/pkg/active/bin/ out of your PATH.

That will prevent the scripts installed in that directory from accidentally taking precedence over the ones installed by homebrew.
