mysql ruby gem problems on OSX

To get mysql ruby gem working on leopard with default leopard ruby and mysql’s binary distro.

1) Firstly need to make the gem as intel only not fat (cause probably don’t have libraries to make the PPC version - and in any case, why?)

sudo su -

ARCHFLAGS='-arch i386' gem install mysql — –with-mysql-config=/usr/local/mysql/bin/mysql_config

2) Secondly need to fix some internal magic name:

sudo install_name_tool -change /usr/local/mysql/lib/mysql/libmysqlclient.15.dylib /usr/local/mysql/lib/libmysqlclient.15.dylib /Library/Ruby/Gems/1.8/gems/mysql-2.7/lib/mysql.bundle
