getBitmapDataPlanes not recognized?

[Daniel Hazelbaker]

I have a program that, apparently, calls getBitmapDataPlanes: method  
on an NSPICTImageRep.  Nowhere in my own code is that method called so  
it must be called from an AppKit or Quicktime APi that I use.  About 2  
or 3 months ago I installed one of the Quicktime updates on my  
development computer.  Ever since then computers that try to run my  
program (I am developing using XCode 2.5 and the 10.4uSDK) that do not  
have the latest Quicktime installed get this exception:

*** -[NSPICTImageRep getBitmapDataPlanes:]: selector not recognized  
[self = 0x1679f030]

Is there a way to force my program to use the 10.4 "native" Quicktime  
API instead of what is available on my computer?  I am linking to the  
QTKit, Quicktime and QuartzCore frameworks in /System/Library/ 
Frameworks, but shouldn't the linker be using the ones under the  
SDKROOT automatically?
