Warning: Your XQuartz (2.7.4) is outdated
Please install XQuartz 2.7.5:
  https://xquartz.macosforge.org

Warning: /usr/local/share/python is not needed in PATH.
Formerly homebrew put Python scripts you installed via `pip` or `pip3`
(or `easy_install`) into that directory above but now it can be removed
from your PATH variable.
Python scripts will now install into /usr/local/bin.
You can delete anything, except 'Extras', from the /usr/local/share/python
(and /usr/local/share/python3) dir and install affected Python packages
anew with `pip install --upgrade`.

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: 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/libgtsam.2.3.0.dylib

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/libCppUnitLite.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:

    erlang-r16
    lua52
    msp430-binutils
    msp430-gdb
    osxfuse
Error: No available formula for ogre
