cd /usr/local/mysql/lib
mkdir mysql
cp libmysqlclient.15.dylib mysql/libmysqlclient.15.dylib

Hi Philipp, tried to use your solution but got the following error. I’m on a Leopard clean install.

———————-
Building native extensions. This could take a while…
ERROR: While executing gem … (Gem::Installer::ExtensionBuildError)
ERROR: Failed to build gem native extension.

ruby extconf.rb install mysql — –with-mysql-config=/usr/local/mysql/bin/mysql_config
extconf.rb:1: command not found: /usr/local/mysql/bin/mysql_config –cflags
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

I came up with a “less intrusive” solution:

It boils down to

sudo bash -c “ARCHFLAGS=’-arch i386′ gem install mysql …”

Thanks Philipp this worked great. I had to add a couple of lines to get it to work on my machine see below.

cd /usr/lib/ruby/1.8/universal-darwin9.0/
sudo mv rbconfig.rb rbconfig.rb.orig
sudo chmod 777 /usr/lib/ruby/1.8/universal-darwin9.0/
sudo sed “s/-arch ppc//g” rbconfig.rb.orig > rbconfig.rb
sudo chmod 755 /usr/lib/ruby/1.8/universal-darwin9.0/
sudo gem install mysql — –with-mysql-config=/usr/local/mysql/bin/mysql_config
