Sorry, this should read: .. using the kmplayer plugin with konqueror ..

Yes, it's in kmplayercommon.so and it's declared as
  class KMPLAYER_EXPORT PartBase : public KMediaPlayer::Player
and
 #define KMPLAYER_EXPORT KDE_EXPORT
in case of
 #if __GNUC__ - 0 > 3 || (__GNUC__ - 0 == 3 && __GNUC_MINOR__ - 0 > 3)
which should be the case for gcc-4.0.2

Actually I forgot about this class export, but it's there already.
Strange, because I got it working by adding KDE_EXPORT in this
kmplayerpartbase_skel.cpp .... hmm. after doing 'make clean && make
install' it suddenly works.
Darn, I don't understand because I did do 'make -f Makefile.cvs;
./configure --whatever; make install'. This, because of a dcop change
somewhere else in the sources (other source file, other classes).
Maybe, it's the editing of kmplayerpartbase_skel.cpp that did it (but I
did do a 'make clean' a few times too), hmm ..
