Commit ee2c3ab ("Remove spurious libiconv dependencies") pruned all existing "depends_on 'libiconv'" usages from Homebrew in preparation for removing the libiconv dupe itself. Now that is done, and we can remove and blacklist it. It can be obtained from Homebrew-alt. Closes #10464. Signed-off-by: Jack Nagel <email@example.com>
We don't penalise existing users; if ~/Library/Caches/Homebrew already exists and is writable, we select that. This is the correct choice, the cache should be the same directory whichever user is used and whatever instance of brew is invoked. The Cache directory is set to 0777 this allows any user to write to it and fixes #10857.
