in your forum's PHP Info page, you should see under ther ctype section,
Code
ctype functions 	enabled

The engineers supporting our platform had to manually deploy it. These links helped to quickly orient the support engineer on what was missing. They have indicated that future updates to PHP in our environment will now include this module. Thanks again for the quick turn on issue resolution.
