I am a longtime Opera user on Linux and Windows and I don't think I've *ever* used a Vector or Slackware package for Opera. What I always do is click on the Download link on Opera's Web site. I select Other/Static RPM as my distribution and vendor and I have a bullet beside Static QT Package and "Download this package in TAR.GZ format." I download to my usual download directory. I then highlight the opera tar.gz file in Midnight Commander, hit F2 and have it Unpack selected file. I then switch to the directory created by unpacking, hit Control-o to get a terminal window in Midnight Commander, su to root, and type ./install.sh (or whatever the correct capitalization is). I use the default directories and type yes (y) for everything. Then I do ldconfig at a prompt, type exit to return to running as user, and type opera at a prompt. No error messages--I'm good to go. Then I type Control-o to return to Midnight Commander. When I'm confident that everything is working, I start Midnight Commander as root, switch to /usr/lib/opera, and delete the directory for the old version.
There's no need to use a Vector or Slackware package for Opera and therefore no need to wait for somebody to package it.
