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.

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.

Some "config" scripts were found in your path, but not in system or Homebrew folders.

`./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.

/usr/X11R6/bin
    freetype-config libpng-config libpng12-config xft-config

/Library/Frameworks/Mono.framework detected

This can be picked up by Cmake's build system and likely cause the
build to fail, finding improper header files for libpng for instance.
