Already up-to-date.
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!

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:

    /opt/sci/anaconda/bin/curl-config
    /opt/sci/anaconda/bin/freetype-config
    /opt/sci/anaconda/bin/libdynd-config
    /opt/sci/anaconda/bin/libpng-config
    /opt/sci/anaconda/bin/libpng15-config
    /opt/sci/anaconda/bin/llvm-config
    /opt/sci/anaconda/bin/nc-config
    /opt/sci/anaconda/bin/python-config
    /opt/sci/anaconda/bin/python2-config
    /opt/sci/anaconda/bin/python2.7-config
    /opt/sci/anaconda/bin/xml2-config
    /opt/sci/anaconda/bin/xslt-config

Warning: You have a curlrc file
If you have trouble downloading packages with Homebrew, then maybe this
is the problem? If the following command doesn't work, then try removing
your curlrc:
  curl http://github.com
