Ever had a problem compiling php5-simplexml on a FreeBSD system?. If you’ve been having trouble and the compiller complaining about not finding something related with a php extension named “spl”; Congratulations, you’ve been googling and found the right place to tell you: Upgrade your PHP to a 5.3.x version, since the SPL extension was removed.

Check the PHP5 Changelog and look for php 5.3.0:

Improved SPL extension:

• Added SPL to list of standard extensions that cannot be disabled. (Marcus)

Will save you lots of time…
