Well I deleted /usr/lib32/qt4/libQtOpenGL.so.4.6.2 and ran
revdep-rebuild and got the following
. . .
* Checking dynamic linking consistency
[ 39% ]  *   broken
/usr/lib32/qt4/plugins/graphicssystems/libqglgraphicssystem.so (requires
libQtOpenGL.so.4)
[ 100% ]
* Generated new 3_broken.rr
. . .
* All prepared. Starting rebuild
emerge --oneshot  --jobs=2 --with-bdeps y
app-emulation/emul-linux-x86-qtlibs:0
..........
Calculating dependencies... done!

After revdep-rebuild finished the library was back.
