I'm also using 4.1.2. I have 4.2.x installed because KDE4 requires that 
version of the C++ libs (with openSuSE 10.2 anyway), but the one time I tried 
to compile PyKDE4 using 4.2, it hung (with concatenated files). It may work 
with sip generating individual files or splitting into a large number of 
parts may work too. I haven't looked into it any farther because PyKDE4 is 
still about 3 months away from release.

PyKDE3 had the same problem with early 4.0.x versions, and still detects those 
and doesn't concatenate for those versions.
