MySQL Gem - x86_64-linux

Can somebody tell me how to get the MySQL Gem to build its native
extensions under x86_64 linux?

I say:
gem install mysql – -with-mysql-dir=/usr/lib64/mysql

I get:

checking for mysql_query() in -lmysqlclient… no
checking for main() in -lm… yes
[…]
*** 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.

Urk, never mind. The right thing to do was apparently

gem install mysql – -with-mysql-config=/usr/bin/mysql-config

(Though I actually did this in the install directory via setup.rb.)
