A working IBM WebSphere MQ installation. If building the extention the SDK
for IBM WebSphere MQ is also required.
Note:
Be aware that when running against a IBM WebSphere MQ Client installation
some methods are not available. This is not a problem of the extention but
just the way the WebSphere MQ Client Interface works.
Installation requirements on non windows platforms
Build the extention and put it in the PHP extention directory.
