After upgrading to OS X 10.9 Mavericks, ant is no longer on my path.
 11:23:26 rkarl-mba-4:~/mobile-baselayer > ant zsh: permission denied: ant  11:23:50 rkarl-mba-4:~/mobile-baselayer > which ant ant not found
I tried installing through homebrew
 11:23:09 rkarl-mba-4:~/mobile-baselayer > brew install ant Error: No available formula for ant
It's odd that homebrew doesn't have a formula for that....
After googling, I found this article, which suggested using a user's custom formula for brew.
 11:23:56 rkarl-mba-4:~/mobile-baselayer > brew install https://raw.github.com/adamv/homebrew-alt/master/duplicates/ant.rb curl: (22) The requested URL returned error: 404 Not Found Error: Failure while executing: /usr/bin/curl -f#LA Homebrew\ 0.9.4\ (Ruby\ 1.8.7-358;\ Mac\ OS\ X\ 10.9) https://raw.github.com/adamv/homebrew-alt/master/duplicates/ant.rb -o /Library/Caches/Homebrew/Formula/ant.rb
Any help would be appreciated!
