Qt3 - No Longer Builds (multiple boxes) libkdecore.so.4: undefined symbol: _ZN7KGlobal20deleteStaticDeletersEv

Guys,

   This is bizarre. I went to build Qt3 this morning, applied a new patch, and 
Qt3 wouldn't compile. So I removed the patch just to make sure nothing on the 
system had changed to prevent building and -- I STILL GET THE ERROR??

   So I went to a box where Qt3 built a day or so ago which still had the Qt3 
build directory in place from the last time it built and went to build it again 
- I get the same symbol lookup error.

   The only thing that changes was qt 4.7.3-1 was pulled in as a dependency of 
poppler-qt when I attempted to build kdegraphics with -DWITH_PDF=ON.  I thought 
Qt3 would build fine with Qt4 installed?  Is this something new with the new 
version?

   The symbol error has me scratching my head. I can't for the life of me figure 
out what this error is telling me:

   I get that it is a uic symbol lookup error:

/home/david/tblds/trinity-qt3/src/qt-x11-free-3.3.8b/bin/uic: symbol lookup 
error: /opt/trinity/lib/libkdecore.so.4: undefined symbol: 
_ZN7KGlobal20deleteStaticDeletersEv

   How does one fix a symbol lookup error like this?

   Also why does the Qt3 build even look to /opt/trinity/lib/libkdecore.so.4? 
How can I prevent this from happening? This built fine before the Qt4 package 
installed. Short of removing Qt4, what is the best way to try and fix this?

   The build script is here:

http://svn.trinitydesktop.org/svn/trinity-packaging/arch/master/trinity-qt3/PKGBUILD

   The Qt3 package built fine when I uploaded it a day ago:

http://svn.trinitydesktop.org/svn/trinity-packaging/arch/master/src/trinity-qt3.tar.gz

   Any help appreciated :)
