homebrew -- fix that nasty mysql.server start segfault

after install xcode 4.3 mysql.server start was shouting back at me and refusing to start: ERROR! The server quit without updating PID file

installing the old, non llvm, gcc binaries and re-installing seemed calm the beast

brew remove mysql brew cleanup brew update brew upgrade brew install https://raw.github.com/Homebrew/homebrew-dupes/master/apple-gcc42.rb brew install mysql

also, dont forget to follow the instructions after install

unset TMPDIR mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
