I was wondering if anyone else has figured out how to solve this problem. Whether I install the extension via PECL or compile it by hand, I get the same error:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/zend/lib/php_extensions/gearman.so' - dlopen(/usr/local/zend/lib/php_extensions/gearman.so, 9): no suitable image found. Did find:
/usr/local/zend/lib/php_extensions/gearman.so: mach-o, but wrong architecture in Unknown on line 0
I have no idea how to fix this problem and I can only bang my head into my desk so many times.
After getting help from the people I follow in Twitter, Ralph Schindler from Zend talked me through how to do this via Skype chat:
