You need to implement methodSignatureForSelector in PCAppController.m like this ...

- (NSMethodSignature*) methodSignatureForSelector: (SEL)aSelector
{
NSMethodSignature	*sig;

sig = [super methodSignatureForSelector: aSelector];
if (sig == nil)
{
sig = [menuController methodSignatureForSelector: aSelector];
}
return sig;
}

You also need the latest GNUstep base and gui code from CVS (by latest, I mean I just comitted some fixes).
