Apple released an update to Lion bringing it to version 10.7.3 and introduced a security update to Snow Leopard. If you followed the latest set of instructions where everything was located in /usr/local then these updates wouldn’t have affected you. However for all the people who are still on the original setup you will have been impacted as this security update installs and overwrites PHP and Postfix. The solution to this is still the same go into the source directory of the last installed version and run a “sudo make install” for PHP and Postfix, restart Apache and Postfix and everything is back in order again. You might also need to comment out the line:
inet_interfaces = localhost
Try to migrate as soon as possible to the new setup to save you from future problems with the next security update.
The funny thing is that when you read the content of the security update details you will see that if you followed our update strategy you will use more recent stuff for your web and mail server then is included in this update. Example: After the update you will have Apache 2.2.21 while we are on 2.2.22 and the buid in PHP will be updated to 5.3.8 while we are on 5.3.10. This proves my point that you are better of doing this kind of stuff yourself without waiting for Apple or someone else to provide you with the updates.
Here you don’t even need me, I only help in the testing and eventual problem fixing if something goes wrong…
