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.

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:

    imagemagick
Warning: Some installed formula are missing dependencies.
You should `brew install` the missing dependencies:

    brew install libpng

Run `brew missing` for more details.
Warning: Some directories in your path end in a slash.
Directories in your path should not end in a slash. This can break other
