I\'m currently trying to get MySQL working on OSX 10.7 Lion. I tried the brew way:
brew install mysql -> cmake -> no problems -> make
I had MySQL installed already, but after upgrading to Lion it would no longer start.
I tried installing the latest official version and it still wouldn't start.
Finally, this fixed it:
$ sudo mkdir /var/log/mysql $ sudo chown mysql:mysql /var/log/mysql
