Error: "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:

    /usr/local/rvm/gems/ruby-1.9.3-p194/bin/passenger-config
    /opt/sm/pkg/active/bin/curl-config
    /opt/sm/pkg/active/bin/ncurses5-config
    /opt/sm/pkg/active/bin/ncursesw5-config
    /opt/sm/pkg/active/bin/pkg-config
    /opt/sm/pkg/active/bin/xml2-config
    /opt/sm/pkg/active/bin/xslt-config
Error: The following libiconv files were detected in /usr/local:
include/iconv.h
Homebrew doesn't provide a libiconv formula, and expects to link against
the system version in /usr/lib.

If you have an alternate libiconv, many formulae will fail to compile or
link, especially if it wasn't compiled with the proper architectures.
Error: Some keg-only formula are linked into the Cellar.
Linking a keg-only formula, such as gettext, into the cellar with
`brew link f` 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
    libxslt
Error: 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:

Error: Unbrewed .la files were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when

Error: Unbrewed static libraries were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when

Unexpected static libraries:

Error: /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:

    iconv
    xml2-config
    xmlcatalog
    xmllint
    xslt-config
    xsltproc

Consider amending your PATH so that /usr/local/bin
is ahead of /usr/bin in your PATH.
Error: Homebrew's sbin was not found in your path.
Consider amending your PATH variable so it contains:
  /usr/local/sbin
