I did an install of Mandriva 2007 instead of upgrading from 2006. I tried Cooker briefly, but didn't like it since it seemed a little unstable.
I had Opera in 2006 and also on 2007 Cooker, but I can't install it now. I have tried installing it from a binary as well as using the install.sh supplied in the tar file, but they both fail.
When I try to start Opera (after I use 'install.sh') I get this error:
ERROR: ld.so: object 'libjvm.so' from LD_PRELOAD cannot be preloaded: ignored.
ERROR: ld.so: object 'libawt.so' from LD_PRELOAD cannot be preloaded: ignored.
/usr/lib/opera/9.10-20061214.6/opera: error while loading shared libraries: libqt-mt.so.3: cannot open shared object file: No such file or directory

If I try to install from the software installer in Firefox when I go to OPera's website it says that it can't be installed due to un-satisfactory libqt-mt.so.3.

This file can be found in:
/usr/lib/qt3/lib64/libqt-mt.so.3
and my path is
/sbin:/usr/sbin:/bin:/usr/bin:/usr/X11R6/bin:/usr/local/bin:/usr/local/sbin:/usr/lib/qt3//bin:/usr/lib/qt3/lib64
I find this strange, and annoying, since I have installed Opera 9 on x64 before. Any suggestions?

I installed 2006 official since I had a some problems with the applications I used most in 2007.
I was able to install Opera in 2006 (same version of Opera), so there seems to be a bug in 2007 that has been fixed in 2007 Cooker. Since I don't know what the fix is I am not ready to update to Cooker since I prefer to be on the safe side.
