So it looks like these functions were available first in iOS 2, and according to Apple documentation did not become available in Mac OS X until 10.6.
Ah, that explains it.

The typical solution would be to wrap the relevant code with:
#if defined(MAC_OS_X_VERSION_10_5) && MAC_OS_X_VERSION_MAX_ALLOWED >= MAC_OS_X_VERSION_10_5
Of course, that should be MAC_OS_X_VERSION_10_6 in both places, not MAC_OS_X_VERSION_10_5.
