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.
