Will simply checking NSAppKitVersionNumber from awakeFromNib in my

10.1.x, get to init or awakeFromNib to check NSAppKitVersionNumber
(before any incompatible APIs are called), and if necessary, call
NSRunCriticalAlertPanel then exit gracefully?
No. 10.1.x did not support weak linking, so the app will fail to
launch (dyld will complain about unresolved symbols)

Thanks for the explanation. I just found this tech note:
http://developer.apple.com/technotes/tn2002/tn2064.html
Perhaps, it needs updating? I haven't thoroughly read it.
I don't think I will spend too much more time on this because this
issue will only affect my pre-10.2 users.
Day after tomorrow I will be at the ADC Compatibility Lab at Apple.
If someone wanted to give me a little version-checking app, I
should/might have time to test it on many different Mac OS X versions
(as long as this solution is shared with everyone).
Chuck
