This means that the code being built is trying to use a function called 
ServiceBrowser() and it's failing because it doesn't exist or is defined to be 
something different to what the code expects.

Those are useful things to do often anyway, but all too often they are 
presented as the MagicBandAid(tm) solution to all build failures, world hunger 
and stuff that eats kittens. I doubt very much is they will help as none of 
those tips affect compiled libs already in place.

kdelibs-3.5 on Gentoo had some outlandish requirements - zeroconf was one of 
them. I don't rightly recall which zeroconf method it was - zeroconf, 
mDNSResponder, avahi - but stuff broke horribly without it. What does eix say 
about KDE-3.5 packages using any of those flags? I don't have 3.5 around 
anymore to check here

Also, KDE is heavily interlinked with Qt. A Qt upgrade usually implies a 
rebuild of all of KDE being a very good idea. It's not in DEPEND as KDE 
doesn't so much require a specific Qt version, it's that the built KDE now has 
to work with A higher version of Qt than it was build against. Did you 
recently upgrade Qt?

Have you rebuilt kdelibs than tried building kdegames again?

<side-step workaround>
Have you asked the question "Do I really need all of KDE games?"
