The TeXLive Package Manager, i.e. tlmgr(1), is not shipped with this TeXLive package, as it's not expected to work properly (if at all). The general consensus from the TeXLive users mailing list is that distributions should not be shipping tlpkg. The *proper* way to upgrade the TeXLive Slackware package (or any part of it) is through your Slackware's package manager. If you elect to try tlmgr(1), and it doesn't work at all, or worse, it messes up part of your TeXLive installation, too bad. On the other hand, if you are able to document exactly what we need to do in order to make it: 1) work 2) put updates and such in a user-specific directory, i.e. *not* alter/replace system package contents then we would love to hear from you. :-) --rworkman :-)
