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/libclucene-core.2.3.3.4.dylib
    /usr/local/lib/libclucene-shared.2.3.3.4.dylib
    /usr/local/lib/libechonest.1.1.4.dylib
    /usr/local/lib/libechonest.1.1.5.dylib

We couldn't detect gcc 4.0.x. Some formulae require this compiler.

/usr/bin is in your PATH before Homebrew's bin. This means that system-
provided programs will be used before Homebrew-provided ones. This is an
issue if you install, for instance, Python.

Consider editing your .bashrc to put:
  /usr/local/bin
ahead of /usr/bin in your $PATH.

Some brews install binaries to sbin instead of bin, but Homebrew's
sbin was not found in your path.

Consider editing your .bashrc to add:
  /usr/local/sbin
to $PATH.
