sip for el6 in kde-unstable

[John Pilkington]

Hi Rex: I would quite like to have the smart package manager GUI 
available.  It requires PyQt, which requires sip-api(6)=6.0

That is provided by sip-4.9.3-1.el6.i686 from sl, but not by 
sip-4.14.6-1.el6.i686 from kde-unstable.

In all other respects the kde-unstable packages work very well for me. 
Is this sip conflict an essential part of the unstable packages?

Thanks,

John P
