brew doctor 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:

    /Library/Frameworks/Python.framework/Versions/2.7/bin/python-config
    /Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7-config
Warning: gettext was detected in your PREFIX.
The gettext provided by Homebrew is "keg-only", meaning it does not
get linked into your PREFIX by default.

If you `brew link gettext` then a large number of brews that don't
otherwise have a `depends_on 'gettext'` will pick up gettext anyway
during the `./configure` step.

If you have a non-Homebrew provided gettext, other problems will happen
especially if it wasn't compiled with the proper architectures.
Warning: Unbrewed dylibs were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Warning: /usr/bin occurs before /usr/local/bin
This means that system-provided programs will be used instead of those
provided by Homebrew. The following tools exist at both paths:

    2to3
    idle
    pydoc
    python
    python-config
    pythonw
    smtpd.py

Consider ammending your PATH so that /usr/local/bin
is ahead of /usr/bin in your PATH.
Warning: Homebrew's sbin was not found in your path.
Consider ammending your PATH variable so it contains:
  /usr/local/sbin
