You have unbrewed dylibs in /usr/local/lib. These could cause build problems
when building Homebrew formula. If you no longer need them, delete them:

    /usr/local/lib/libfuse.2.dylib
    /usr/local/lib/libfuse_ino64.2.dylib

You have a non-brew 'pkg-config' in your PATH:
  /usr/local/bin//pkg-config

`./configure` may have problems finding brew-installed packages using
this other pkg-config.

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.
