You should not show an alert if Growl is not installed. If a notification is
essential for the user to see, use an alert instead of the notification.
Remember that the user:
- May not want Growl
- Can turn Growl off
- Can kill the Growl background process
- Can disable your application's notifications
- Can disable any specific notification
- May be using a non-visual display such as Speech, SMS, or MailMe
Notifications should be optional. The user should be slightly inconvenienced
(by having to find out by other means) for missing a notification, not have
their day/use of your application ruined.
If what you have to tell the user is something they *need* to know, it should
be in a dialog box or alert, not a notification.
The only time such an alert might be warranted is if your application exists
solely to send Growl notifications. HardwareGrowler is an example of this. Even
then, I'd say that that information belongs on your product web-page/App Store
listing, not (or at least not just) in an alert. (And no, I don't know whether
such an app would be accepted into the App Store.)
Also, you should use NSLocalizedString for any string you have in code that you
display to the user. This includes alert messages and button titles.

The answer to your question is revealed by rephrasing it:
“If I failed to load the Growl framework, can I still use classes in the Growl
framework?”
