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: gettext was detected in your PREFIX. The gettext provided by Homebrew is "keg-only", meaning it does not get linked into your PREFIX by default.
If you brew link gettext then a large number of brews that don't
otherwise have a depends_on 'gettext' will pick up gettext anyway
during the ./configure step.
If you have a non-Homebrew provided gettext, other problems will happen especially if it wasn't compiled with the proper architectures. 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:
