In that case, you should create symbolic link from recent SDK to /usr/include:

sudo ln -h -f -s 
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/usr/include
 /usr/include

This is required to auto-detect built-in packages.

And you need to provide:

-isysroot 
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk

to compiler flags, and

-Wl,-syslibroot,/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk

to linker flags.

:)

Kind regards,
