It seems that I still don’t have a stable system, since I’ve upgraded to Snow Leopard a few weeks back.

Running db:migrate or entering cmd-R from TextMate fails with the following error:

uninitialized constant MysqlCompat::MysqlRes

I did a few different things, but I it boils down to having to do this:

$ sudo gem uninstall mysql
$ sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/lib/mysql_config

(your mysql_config could be in /usr/local/mysql/bin instead, in which case make sure to use that path)

I’ve also wound up uninstalling mysql and reinstalling, though I don’t think those steps were necessary. Just in case, you might want to try that also. Go here: http://dev.mysql.com/downloads/mysql/5.1.html#macosx and get “Mac OS X 10.5 (x86_64)” from the package format section.
