Я установил homebrew давным-давно и не очень часто его использую, но я думал о том, чтобы начать возвращаться к нему, поскольку это очень полезный и простой в использовании установщик пакетов. В любом случае, я побежал к доктору варки и получил множество предупреждений, которые я не уверен, как это исправить! Я особенно боюсь удалять файлы .dylib, .la и .pc, если они понадобятся моим пакетам, которые не были установлены через homebrew. Любая помощь по этому вопросу будет принята с благодарностью. Если это имеет значение, я использую Mac OS X Mountain Lion (10.8.3), мой список предупреждений выглядит следующим образом:

UOS-12044:~ as34g12$ brew doctor
Warning: /usr/local/include isn't writable.
This can happen if you "sudo make install" software that isn't managed
by Homebrew.

If a brew tries to write a header file to this directory, the install will
fail during the link step.

You should probably `chown` /usr/local/include
Warning: /usr/local/share isn't writable.
This can happen if you "sudo make install" software that isn't managed
by Homebrew.

If a brew tries to write a file to this directory, the install will
fail during the link step.

You should probably `chown` /usr/local/share
Warning: Some directories in /usr/local/share/locale aren't writable.
This can happen if you "sudo make install" software that isn't managed
by Homebrew. If a brew tries to add locale information to one of these
directories, then the install will fail during the link step.
You should probably `chown` them:

    /usr/local/share/locale
    /usr/local/share/locale/be
    /usr/local/share/locale/be/LC_MESSAGES
    /usr/local/share/locale/ca
    /usr/local/share/locale/ca/LC_MESSAGES
    /usr/local/share/locale/da
    /usr/local/share/locale/da/LC_MESSAGES

    /usr/local/share/locale/tr
    /usr/local/share/locale/tr/LC_MESSAGES
Warning: Some directories in /usr/local/share/man aren't writable.
This can happen if you "sudo make install" software that isn't managed
by Homebrew. If a brew tries to add locale information to one of these
directories, then the install will fail during the link step.
You should probably `chown` them:

    /usr/local/share/man/de
    /usr/local/share/man/de/man1
Warning: The /usr/local directory is not writable.
Even if this directory was writable when you installed Homebrew, other
software may change permissions on this directory. Some versions of the
"InstantOn" component of Airfoil are known to do this.

You should probably change the ownership and permissions of /usr/local
back to your user account.
Warning: Setting DYLD_LIBRARY_PATH can break dynamic linking.
You should probably unset it.
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:

    /Library/Frameworks/Python.framework/Versions/2.7/bin/python-config
    /Library/Frameworks/Python.framework/Versions/2.7/bin/python2-config
    /Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7-config
    /soft/star-hikianalia/bin/gsl-config
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:

    fftw
Warning: You have uncommitted modifications to Homebrew
If this a surprise to you, then you should stash these modifications.
Stashing returns Homebrew to a pristine state but can be undone
should you later need to do so for some reason.
    cd /usr/local/Library && git stash && git clean -f
Warning: Some installed formula are missing dependencies.
You should `brew install` the missing dependencies:

    brew install gmp harfbuzz icu4c libmpc mpfr

Run `brew missing` for more details.
