Use your distribution way of installing things (e.g. build deb packages) or 
suffer!

Your best bet is to learn, how to install and build from deb source 
packages, and then replace the tar balls, adjust versions in build script 
and probably the patches.. 

Let's take a look from a car mechanic POV: you're trying to add another 
engine - but how to attach the gearbox with both engines and how to shift 
gears, etc..? Ever saw anything alike? You will want to _replace_ the 
engine, and since Qt is a nice citizen (at least within major release), 
this should be possible without recompiling every bit of software depending 
it!

Alternatively, you may want to search for services, which provide current 
packages for your distribution. Chances are good, that there are the 
matching qscintilla, sip and PyQt packages (because these are attached so 
tightly, that they should be compiled against the exact Qt version).
