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/irix/.rvm/gems/ruby-1.9.3-p392/bin/passenger-config

Warning: You may have installed MacGPG2 via the package installer.
Several other checks in this script will turn up problems, such as stray
dylibs in /usr/local and permissions issues with share and man in /usr/local/.

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/libmacfuse_i32.2.dylib
    /usr/local/lib/libmacfuse_i64.2.dylib
    /usr/local/lib/libosxfuse_i32.2.dylib
    /usr/local/lib/libosxfuse_i64.2.dylib

Warning: Unbrewed .la files 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 .la files:
    /usr/local/lib/libosxfuse_i32.la
    /usr/local/lib/libosxfuse_i64.la

Warning: Unbrewed .pc files were found in /usr/local/lib/pkgconfig.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Unexpected .pc files:
    /usr/local/lib/pkgconfig/fuse-ext2.pc
    /usr/local/lib/pkgconfig/osxfuse.pc

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:

    2to3
    awk
    cdiff
    config_data
    crc32
    ctags
    macdeployqt
    ptar
    ptardiff
    qdoc3
    qt3to4

Consider amending your PATH so that /usr/local/bin
occurs before /usr/bin in your PATH.

Warning: Homebrew's sbin was not found in your path.
Consider amending your PATH variable so it contains:
  /usr/local/sbin
