Everything is working now! Thanks so much for this excellent tutorial! Updating your excellent instructions to include the extra step of downloading xcode command line tools might be helpful for others to avoid the issue I encountered. Thanks again for all your help!!

Cool, if you follow the instructions at the end of the article, you’ll see how to overcome libmysqlclient.18.dylib missing issue.

Xcode was installed, however build 4.6.1 does not include command line tools. So I installed the xcode command line tools and reran your instructions. It worked! (thanks!) Now, in python import MySQLdb I am getting Library not loaded: libmysqlclient.18.dylib. I will now follow your instructions above on how to resolve image not found. Progress!

If Gcc is not found usually means Xcode is not installed, have actually run the install aft downloading Xcode from the App Store?

Followed your instructions (thanks!). This the error I get during the build:

Hi Kent, you seem to be almost there. Sometimes it is necessary to physically remove any old install from your site-packages (wherever it got installed, virtualenv or machice root), delete all “build” folders and files that have been generated from the first install run.
Then I would suggest to re-unzip the source, make the changes in site.cfg and then run setup.py install as normal.
Please try this and let me know if that work for you.

Yes MySQL is installed and working. I followed your tip and also installed Sequel Pro which is now connecting and working very nicely with MySQL (thanks for that tip!). On my first attempt to install MySQLdb I forgot to uncomment the mysql_config = /usr/… in site.cfg when I updated the path to MySQL bin and accidentally ran setup.py install. After realizing this mistake, i corrected site.cfg and reran setup.py install but still no luck.
Appreciate any help you might have.

Hi Kent, did you actually install MySQL on your machine, and made sure that mysql_config in site.cfg points to the right binary? (eg: /usr/local/mysql/bin/mysql_config)
