This kind of problem is usually an indication that the
dsitribution's KDE libs don't define a symbol that PyKDE does
define. PyKDE is developed from KDE sources downloaded from a
*.kde.org web site. In addition, recent versions of PyKDE are
test built (successfully) against Mdk 9.1, but there appear to
different versions of the KDE libs in different versions of Mdk

No - this is a known problem with PyKDE on Mandrake. Basically
this constructor was made private in KDE 3.1.1, but Mandrake
picked up the change in KDE 3.1.0. All you need to do is open
kservice.sip in an editor, and find these lines:
%If ( KDE_3_1_1 - )
KService (const KService&);
And change it to:
%If ( KDE_3_1_0 - )
The line numbers may vary depending on the PyKDE version, but it
should be right near the top of the KService class defintion at
the beginning of the file.

The other possible problem to checkout is in
kaboutapplication.sip. Open that in an editor, search for
"QXEmbed" and comment out the line that contains it ("//"
comment). This is an error on my part and should only affect the
As far as I know, there shouldn't be any other Mdk related
problems. I'm not sure of the cause of the rpm problem (I don't
do the rpms), but it's probably related to differences between
the packager's KDE libs and yours.
You do need to be sure that you're installed PyQt and sip are
v3.7, but that doesn't seem to be a problem in your case. If the
"copyrightStatement" bug shows up again after you compile, you
can comment out that method in kaboutdata.sip (given the time it
takes to compile, you might want to do that anyway, unless you
desperately need that method).
Sorry for the difficulities - I haven't figured out any way to
catch this kind of stuff before releasing. Post again if you
still have problems.
