Can't 'make' in KPSK PSK31 for KDE3.x

I've downloaded KPSK version 1.0.1 from http://kpsk.sourceforge.net/

Command './configure' executed OK

Command 'make' gives me following error messages:
logcore.cpp
logcore.cpp: In constructor `logCore::logCore()':
logcore.cpp:33: error: cannot convert `char*' to `DB_TXN*' in argument
passing
logcore.cpp:40: error: cannot convert `char*' to `DB_TXN*' in argument
