When trying to load in the Redis module for his PHP installation, Jim Plush was getting an error:

PHP Warning: PHP Startup: Unable to load dynamic library '/[...]/redis.so' - dlopen(/[...]/redis.so, 9): no suitable image found. Did find: /[...]/redis.so: mach-o, but wrong architecture in Unknown on line 0

He fixed the issue with the help of a bash script (source included) that sets up the right environment to build PHP on the OSX platform. Then the normal make, phpize, etc process can be done on the PECL extension and have it compile correctly.
