tdenetwork ftbfs

I'm attempting to build 'tdenetwork' from the latest git source but it's failing. The errors begin with; tdenetwork/kopete/protocols/groupwise/libgroupwise/securestream.h:43:22: error: QCA has not been declared I've seen this mentioned in recent list history but from what I read, it was apparently fixed. As mentioned in the posts I read, it builds successfully with; -DBUILD_KOPETE_PROTOCOL_GROUPWISE=OFF -DBUILD_KOPETE_PROTOCOL_JABBER=OFF but that is surely not the answer? I have _fairly_ recently built this but not on x86_64. Anybody any pointers? MIke. -- Any question is easy if you know the answer!
