Apparently, though unproven, at 23:19 on Wednesday 08 September 2010, dhk did

In that case, I think you need to conclude that  emul-linux-x86-qtlibs is 
built to link to libGL which you don't have and which you can't fix (it's a 
binary package). So you could 

- delete /usr/lib32/qt4/libQtOpenGL.so.4.6.2 as I doubt you are running 32 bit 
Qt apps, or 
- use SEARCH_DIRS_MASK to tell revdep-rebuild to just ignore that file
