Trying to update Homebrew with brew update I got the following error

I found a blog post by someone who experienced a similar problem after having installed Mountain Lion (which I did this week too). He explains how he removed the files referred to in the error message
I removed these files: $ cd $(brew --prefix) $ rm cocot.rb However, removing these files didn t help with the brew update. Instead I had to manually update brew through git: $ cd $(brew --prefix) $ git fetch origin $ git reset --hard origin/master $ brew update Already up-to-date.
Assuming those instructions are correct (which I maybe shouldn t assume), I tried to follow these instructions and do
$ cd $(brew --prefix)
$ rm cocot.rb
However, it said file doesn t exist when I tried to rm cocot.rb
One thing I m not sure about is the cd $(brew --prefix) Are those the exact words I type or do I have to replace prefix with something? the cd was successful, so I m assuming it was correct -- it moved me into /usr/local, but there was no file to remove. Contents of /usr/local are
Cellar clamXav git mysql var Library doc heroku mysql-5.5.15-osx10.6-x86_64 README.md etc include rvm bin foreman lib share
At any rate, do you know how I can fix the brew update
Update: After removing the files according to favoretti s instructions and trying chown -R <your_username> $(brew --prefix)/.git, I got the following error running brew update
