I am stuck

I have been trying to compile the latest version of kde from cvs - but 
kdegraphics has got me beat since about last Tuesday.  

I had a problem with libpng between version 2 and 3 - but this is now sorted 
and I have rebuild kdelibs so that it properly links with libpng.so.3 
(libqt-mt is too).  This is installed in the default place /usr/local/kde/lib 
and my LD_LIBRARY_PATH has this and the qt-copy/lib as the two library paths 
(and I am sure thats right, because all the other modules such as kdebase etc 
build without problems).  KDEDIR is set to /usr/local/kde.

But - my make of kdegraphics continually fails with the following errors 
inside libkscan

.libs/gammadialog.o: In function `GammaDialog::GammaDialog(QWidget *)':
.libs/gammadialog.o(.text+0x55): undefined reference to

Both KDialogBase and KIconLoader are core classes within kdelibs - I can see 
no reason why this compilation should fail.  Indeed as in the previous thread 
on the kde user mailing list about this others seem not to have any problems.

As far as I can see from the make output the correct libraries (at least 
KDialoogBase is in libkdeui) are being used. Here is the line from make that 
seems to cause the above errors and /usr/local/kde/lib/libkdeui.so is listed 
as an input to this link

-Wl,/usr/local/kde/lib

Unfortunately, I find the way makefile.am is constructed fairly opaque and 
there is not any guiding docs that I have been able to find.

Can someone help me through this please
