#
# What doctor said:
#
# Error: 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 installing something via sudo or a pkg, and it took ownership of a
# bunch of share folders. You'll want to chown them back to your user.
#
# The following command should set the correct ownership and group for all files and directories
# below and including `/usr/local/share`
sudo chown -R $(whoami) /usr/local
