Snow Leopard gives me a headache! (Ruby/MySQL/DBI)

So, needed to create tiny Ruby script which will work with MySQL via DBI. It almost ate my brain. Didn't want to work! But I can swear that it did work before (until I upgraded to Snow Leopard!). Found this link http://freaking.hilbrink.org/?p=7 and it happened to be my problem:

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

So easy and stupid :-(
Works now.
