It needs rpm to build the package.

/usr/src/opera-11.10/SLKBUILD uses tar.xz from opera site, but slapt-src's newer opera package uses rpm. It would be simplier if the packager use tar.xz as "source" (as he did with 11.10) and not rpm. Can you fix this?
Another question. What's the policy about binary package upgrades in Salix? Firefox upgraded from 4.0 to 4.0.1 in Salix binary repo, why not Opera?
Note: I'm an advanced Linux user, I can update SLKBUILD file to 11.11, or make SlackBuild script, but I've installed Salix for beginner users and it would be better if Salix official repo include this update, so salix-update-notifier notifies these kind of users about update and they can upgrade with some clicks without unofficial repo or without the need of install package manually with spkg.
