Just a few days ago, I had the opportunity to upgrade my iMac from a 20” to a 24”. Not only does it have more real estate on the screen, not only is the CPU slightly faster, but it also can take up to 3 Gb of RAM, from 2Gb, which is quite an improvement, especially if you like to run multiple VMs (using Parallel).
So it was quite a relief to us my notes to install Rails on Mac OS Tiger. Except that a lot has changed in the past 3 months since I last wrote that article, and before I update the page to make more sense to newcomers, I’ll just write down a few notes on what I had to do differently.
These reflect the installation on MacOS 10.4.8 and the latest version of MacPorts (as of 10/14/06).
First of all, Darwin Ports is no more: long live MacPorts!
Which means that here is a new location for darwin ports installer.
Then I uncovered a problem in the order of the steps:
Set the PATH before running “sudo port -d selfupdate”, not after as suggested.
One thing that I did not realize, is that you need to actually install a C compiler before you can get started! The easiest is to install XCode 2.4. There is a free registration you need to fill in.
I missed a sudo:
cp httpd.conf.sample httpd.conf => sudo cp httpd.conf.sample httpd.conf
The path to the launchctl file for apache2 has changed:
sudo launchctl load -w /Library/LaunchDaemons/org.macports.apache2.plist instead of sudo launchctl load -w /Library/LaunchDaemons/org.darwinports.apache2.plist
To initialize the database, you need to add:
add "sudo -u mysql mysql_install_db5"
The path to the launchctl file for mysql5 has changed as well:
sudo launchctl load -w /Library/LaunchDaemons/org.macports.mysql5.plist instead of sudo launchctl load -w /Library/LaunchDaemons/org.darwinports.mysql5.plist
replace rb-mysql5 with rb-mysql since rb-mysql supports both flavors
And that’s where it got a bit tricky. With that combination of MacOS 10.4.8 and the current version of MacPorts, rb-mysql fails to compile.

make: *** [mysql.o] Error 1
At this point your are either stuck waiting for an update version, or if you are not afraid to dip into the code, you can arm-twist it into working by following these steps:
rb-mysql patch
These steps should be fairly simple to follow:
cd /opt/local/var/db/dports/build/_opt_local_var_db_dports_sources_rsync.rsync.darwinports.org_dpupdate_dports_ruby_rb-mysql/work/mysql-ruby-2.7.1
sudo ruby extconf.rb --with-mysql-include=/opt/local/include/mysql5/mysql/ --with-mysql-lib=/opt/local/lib/mysql5/mysql/
add '#include "my_global.h"' to mysql.c (as the first #include)
sudo make clean
sudo make
sudo make install
And voila. Running the tests will show 3 failing tests, mostly due to imprecisions, but I think you can live with them. Further testing with rails apps did not reveal any problems with MySQL access.
Note: I’ve contacted the maintainer of that port but I have not heard back yet. I will update this post when I do.
A few bonus gems I’ve found helpful, or can’t live without
And since you are in setup mode, you might as well add them to your collection.
