brew doctor
----------------------------
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!

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/ImageMagick/bin/Magick++-config
  /opt/ImageMagick/bin/Magick-config
  /opt/ImageMagick/bin/MagickCore-config
  /opt/ImageMagick/bin/MagickWand-config
  /opt/ImageMagick/bin/Wand-config

Warning: Putting non-prefixed coreutils in your path can cause gmp builds to fail.

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.

Unexpected dylibs:
  /usr/local/lib/libpixman-1.0.dylib
  /usr/local/lib/libsox.3.dylib

Warning: Unbrewed header files were found in /usr/local/include.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Unexpected header files:
  /usr/local/include/python3.5m/pygame/_camera.h
  /usr/local/include/python3.5m/pygame/_pygame.h
  /usr/local/include/python3.5m/pygame/_surface.h

Warning: Unbrewed .la files were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when

Unexpected .la files:

Warning: Unbrewed .pc files were found in /usr/local/lib/pkgconfig.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Unexpected .pc files:
  /usr/local/lib/pkgconfig/fuse-ext2.pc

Warning: Unbrewed static libraries 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.

Unexpected static libraries:
  /usr/local/lib/libpixman-1.a
  /usr/local/lib/libsox.a

Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
  dosbox-x
  emacs-mac
  mercurial
  qemu
  scipy
  sox

Warning: Broken symlinks were found. Remove them with `brew prune`:

Warning: Some keg-only formula are linked into the Cellar.
Linking a keg-only formula, such as gettext, into the cellar with
`brew link <formula>` will cause other formulae to detect them during
the `./configure` step. This may cause problems when compiling those
other formulae.

Binaries provided by keg-only formulae may override system binaries
with other strange results.

You may wish to `brew unlink` these brews:
  ncurses
  homebrew/science/opencv3
