We couldn't detect gcc 4.2.x. Some formulae require this compiler.
NOTE: Versions of XCode newer than 4.2 don't include gcc 4.2.x.

Some folders 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
folders, 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

Some "config" scripts were found in your path, but not in system or Homebrew folders.

`./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.
