Error: Setting DYLD_LIBRARY_PATH can break dynamic linking. You should probably unset it. 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.
This asks you to disable the dynamic load path. You can do this by finding out where you installed and uninstalled it. Most likely you have a line in ~ / .bashrc or ~ / .bash_profile that looks like export DYLD_LIBRARY_PATH=/some/path:$DYLD_LIBRARY_PATH
You may wish to brew unlink these brews: libxml2
Brew links create a symbolic link to the installation. This is how you can have python2.6. python2.7, but python will run one of them.
brew unlink libxml2

Error: You have uncommitted modifications to Homebrew core. Unless you know what you are doing, you should run: cd /usr/local && git reset --hard
It says that you made changes to the Homebrew files. Fortunately, Homebrew is stored in Git version control, so you can undo these changes.
cd /usr/local && git reset --hard
Error: Some directories in your path end in a slash. Directories in your path should not end in a slash. This can break other doctor checks. The following directories should be edited: /usr/local/git/bin/
The PATH variable is where your computer looks for programs when you enter it on the command line. You can see your path with echo $PATH .
Standards specify that all paths in PATH should not end with a slash. Thus, homegrown asks you to fix it.
nano ~/.bashrc or nano ~/.bash_profile and search for '/ usr / local / git / bin /' and remove the trailing slash.
