[Qt-interest] QT4.5.1 qtsdk-2009.02 build failure - No QSslSocket functions

[Roger McMurtrie]

When I try to make following  ./configure or ./configure -make libs
make fails with undefined references to  QSslSocket functions such as 
.obj/release-shared/qabstractsocket.o: In function 
`QAbstractSocket::waitForDisconnected(int)':
/home/rmc111/rpm/qtsdk-2009.02/qt/src/network/socket/qabstractsocket.cpp:1817: 
undefined reference to `QSslSocket::waitForDisconnected(int)'

The source file qtsdk-2009.02/qt/include/QtNetwork/QSslSocket contains only 
one line:
#include "qsslsocket.h"

Any ideas on what is wrong?
