      That sounds rather odd. Qt can for sure not remove that function
      from Qt in Qt 4.6.2, that would break their binary compatibility.

      Did you try a fresh compile of KPA? If you still have problems, try
      and join me on IRC, and I'll see what I can do.

      One thing. is this the Qt that the rest of KDE was compiled with,
      or is it a Qt you compiled yourself?

   This was a fresh compile of KPA from a newly checked out sandbox (I
   literally ran cmake . followed by make).  This Qt was installed from
   the same binary repository as the KDE bits.

   I'm going to try installing the debuginfo packages to take a look at
   the symbols there.

The debug library contains the symbol in question:

libQtGui.so.debug
00000000004ac660 t qt_pointSize(double, int)
00000000004038c0 T QFontDatabase::pointSizes(QString const&, QString const&)
00000000003e2ae0 T QFont::pointSizeF() const
00000000003e2a90 T QFont::pointSize() const
00000000003e3990 T QFontInfo::pointSizeF() const
00000000003e39b0 T QFontInfo::pointSize() const

and the link line contains it:

/usr/bin/c++    -Wnon-virtual-dtor -Wno-long-long -ansi -Wundef
-Wcast-align -Wchar-subscripts -Wall -W -Wpointer-arith
-Wformat-security -fno-exceptions -DQT_NO_EXCEPTIONS -fno-check-new
