Differences between opera for Linux

Opera-10.00-b1.gcc4-qt4.i386.rpm
Opera-10.00-b1.gcc4-static-qt3.i386.rpm
One is qt4 and the other is qt3. If your system has qt4/qt3, install the first one or in the shared directory; otherwise, install the static version.

Opera-10.00-b2.gcc4-bundled-qt4.i386. tar.gz.
Opera-10.00-b2.gcc4-qt4.i386.tar.gz
In the bundbled, there are two files: usr/lib/Opera/libqtgui. so.4 and usr/lib/Opera/libqtcore. so.4, and there are several additional lines in Opera:
