I was able to successfully install the mcrypt extension on Mountain Lion but I'm having a difficult time installing the extension on Mavericks.
For reference, I'm following this guide: http://www.coolestguidesontheplanet.com/install-mcrypt-php-mac-osx-10-9-mavericks-development-server/
The only inconsistency I've noticed is that by running php -v from the command line, I'm showing PHP version 5.3.15 - whereas the web server appears to be running 5.4.17. I downloaded 5.4.17 to compile mcrypt.
Basically, everything runs according to plan until the very end. Rather than installing the shared extensions into the new directory, /usr/lib/php/extensions/no-debug-non-zts-20100525, I get a message that says:
Installing shared extensions: /usr/local/lib/php/extensions/no-debug-non-zts-20090626/
EDIT:
The issue appears to be that the web server's PHP was compiled with module API: 20100525 and the system is still using 5.3.15 (which is API: 20090626), hence the error.
I'm assuming you can't (easily) update the system version of PHP. What do I need to do to get the module and PHP APIs to match?
Thanks in advance for any help.
