Brew Update not working after mac 10.9

homebrew

Solution

This fixed it for me

cd `brew --prefix`/Homebrew
git fetch origin
git reset --hard origin/master

brew update worked fine after that

Problem

First time running brew since 10.9 upgrade. From the output below, should I just remove Library/Formula/ant.rb and Library/Formula/apple-gcc42.rb? Also, unclear why git pull is failing. Thanks for any help ``` 525 [projects]$ brew --config HOMEBREW_VERSION: 0.9.4 ORIGIN: https://github.com/mxcl/homebrew.git HEAD: 27c26faf7b958de6028ad55be8ccc5a57b094d3f HOMEBREW_PREFIX: /usr/local HOMEBREW_CELLAR: /usr/local/Cellar CPU: 8-core 64-bit ivybridge OS X: 10.9-x86_64 Xcode: 5.0.2 GCC-4.2: build 5666 LLVM-GCC: build 0 Clang: 5.0 build 500 X11: N/A System Ruby: 1.8.7-358 Perl: /usr/bin/perl Python: /usr/bin/python Ruby: /Users/*****/.rvm/rubies/ruby-2.0.0-p195/bin/ruby 526 [projects]$ brew update error: The following untracked working tree files would be overwritten by merge: Library/Formula/ant.rb Library/Formula/apple-gcc42.rb Please move or remove them before you can merge.
