brew doctor error messages

brew_doc_errors.log

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.
