Linking against HIServices?

I'm trying to use the private API CoreMenuExtraAddMenuExtra(), which 
is compiled into HIServices.  However, adding its umbrella framework, 
ApplicationServices, does not link correctly.  I'm working in Leopard, 
but compiling against 10.4u SDK.

I have the following lines in my header file:


int CoreMenuExtraAddMenuExtra( CFURLRef path, int position, int 
whoCares,int whoCares2, int whoCares3, int whoCares4);
int CoreMenuExtraGetMenuExtra( CFStringRef identifier, void *menuExtra);
int CoreMenuExtraRemoveMenuExtra( void *menuExtra, int whoCares);


but I get a symbol not found error when Xcode tries to link the 
executable. I have linked against ApplicationServices.framework,  grep 
shows that the HIServices binary contains the string 
CoreMenuExtraAddMenuExtra, so I know it's there.  Is there something 
else I need to do?

Thanks,

Josh
