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:

    /Users/dariusz/.rvm/bin/erb-ree-1.8.7-2011.12@ops-config
    /Users/dariusz/.rvm/bin/gem-ree-1.8.7-2011.12@ops-config
    /Users/dariusz/.rvm/bin/irb-ree-1.8.7-2011.12@ops-config
    /Users/dariusz/.rvm/bin/rake-ree-1.8.7-2011.12@ops-config
    /Users/dariusz/.rvm/bin/rdoc-ree-1.8.7-2011.12@ops-config
    /Users/dariusz/.rvm/bin/ree-1.8.7-2011.12@ops-config
    /Users/dariusz/.rvm/bin/ri-ree-1.8.7-2011.12@ops-config
    /Users/dariusz/.rvm/bin/testrb-ree-1.8.7-2011.12@ops-config

Warning: /Library/Frameworks/Mono.framework detected
This can be picked up by CMake's build system and likely cause the build to
fail. You may need to move this file out of the way to compile CMake.

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:

    leiningen

Warning: Some installed formula are missing dependencies.
You should `brew install` the missing dependencies:

    brew install fontconfig

Run `brew missing` for more details.

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:

    autoconf
    autoheader
    bashbug
    c_rehash
    ex
    git
    git-cvsserver
    git-receive-pack
    git-shell
    git-upload-archive
    git-upload-pack
    gitk
    openssl
    pkg-config
    rview
    rvim
    view
    vim
    vimdiff
    vimtutor
    xxd

Consider setting your PATH so that /usr/local/bin
occurs before /usr/bin. Here is a one-liner:
    echo export PATH="/usr/local/bin:$PATH" >> ~/.bash_profile

Warning: You have a non-Homebrew 'pkg-config' in your PATH:
  /usr/bin/pkg-config => /Library/Frameworks/Mono.framework/Versions/2.10.9/bin/pkg-config

This was most likely created by the Mono installer. `./configure` may
have problems finding brew-installed packages using this other pkg-config.

Mono no longer installs this file as of 3.0.4. You should
`sudo rm /usr/bin/pkg-config` and upgrade to the latest version of Mono.

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:

    libxml2
    openssl
    autoconf

Warning: Your Homebrew is outdated.
You haven't updated for at least 24 hours, this is a long time in brewland!
To update Homebrew, run `brew update`.
