gistfile1.txt

First, I don't know why.....but my solution at the moment

cd /usr/local

$ git remote -v
origin  https://github.com/mxcl/homebrew.git (fetch)
origin	https://github.com/mxcl/homebrew.git (push)

$ brew doctor -d
# hangs,stalling, no respond

$ brew update 
# hands,stalling, no respond

$ git remote set-url origin [email protected]:mxcl/homebrew.git
$ # or this works too
$ git remote set-url origin  http://github.com/mxcl/homebrew.git

$ brew doctor
Your system is ready to brew.

$ brew update
Already up-to-date.
