Exception: class 'curl' not found

[jcharaoui]

When attempting to preview the static page from a planned outage, the following PHP exception is raised:

PHP message: Default exception handler: Exception: Class 'curl' not found
Debug:
Error code: generalexceptionmessage
* line 62 of /auth/outage/classes/local/outagelib.php: Error thrown

This appears to fix the problem:
