thanks for the prompt reply.  -lkdeui was the switch i needed.  
however, now, after compiling, my application segfaults whenever it 
tries to instantiate any of several kde parts (including KLineEdit 
and KDatePicker).  strangely, KSqueezedText seems to work fine, and 
stranger still, if i include a KDateTable, the programs will not 
compile.  i get:

[foucault][macho junto]$ make
 g++ -c -pipe -Wall -W -O2  -DQT_NO_DEBUG -DQT_SHARED -DQT_THREAD_SUPPORT -I/usr/share/qt3/mkspecs/default -I. -I/usr/include/kde -I/usr/include/qt3 -I.ui/ -I. -I.moc/ -o .obj/mainform.o .ui/mainform.cpp
.ui/mainform.cpp: In constructor `MainForm::MainForm(QWidget*, const char*,
   bool, unsigned int)':
.ui/mainform.cpp:103: error: no matching function for call to `KDateTable::
   KDateTable(QWidget*&, const char[12])'
/usr/include/kde/kdatetbl.h:251: error: candidates are:
   KDateTable::KDateTable(const KDateTable&)
/usr/include/kde/kdatetbl.h:262: error:
   KDateTable::KDateTable(QWidget*, QDate, const char*, unsigned int)
make: *** [.obj/mainform.o] Error 1

looks like qt-designer decided to call a constructor for KDateTable that doesn't exist.  KDateTable is expecting a date and a name, and it only gets sent a name.

is this still my fault, or is it time to submit a bug report?
