Hi, with mysql.rb removed from rails 2.2 I need to install the mysql  
gem

I have mac osx 10.5.5

I have mysql installed in /usr/local/mysql, so, after a bunch of try,  
I’ve installed  
the gem with:

env ARCHFLAGS="-arch i386" gem install mysql – --with-mysql-config=/  
usr/local/mysql/bin/mysql\_config

the gem seems installed in /usr/local/lib/ruby/gems/1.8/gems/  
mysql-2.7/

but when I try to fire up a command than involves mysql e.g.: rake  
db:create I get this error:

LoadError: Failed to lookup Init function /usr/local/lib/ruby/gems/1.8/  
gems/mysql-2.7/lib/mysql.bundle  
from /usr/local/lib/ruby/gems/1.8/gems/mysql-2.7/lib/mysql.bundle

I also tried with:

env ARCHFLAGS="-arch i386" gem install mysql – --with-mysql-include=/  
usr/local/mysql/include --with-mysql-lib=/usr/local/mysql/lib --with-  
mysql-dir=/usr/local/mysql --with-mysql-config=/usr/local/mysql/bin/  
mysql\_config

and many other ways, but still get the same error.

Any ideas?

Thanks

UPDATE:

After a load of pain and suffer i solved Installing mysql5 client from  
port

sudo port install mysql5

and re-installing the mysql gem with this options:

sudo env ARCHFLAGS="-arch i386" gem install mysql – --with-mysql-  
include=/opt/local/include/mysql5 --with-mysql-lib=/opt/local/lib/  
mysql5 --with-mysql-config=/opt/local/lib/mysql5/bin/mysql\_config

Hope this can help somebody to save some hours of googoling.
