No, it's a problem that's been around and gone through some iterations.  
See http://bugs.python.org/issue9516.  The fix for 2.7 will be in 2.7.2.  
In the meantime, you should be able to work around the problem by 
forcing the environment variable MACOSX_DEPLOYMENT_TARGET to be 10.5 
when you invoke that Python 2.4 from the 2.7 subprocess.
