Recently the site get a new build machine on which the packages for Slackware 11 and 10.2 will be built and prepared. The machine is an old IBM NetVista with an 1 GHz processor and 256 MB of RAM. Currently on the 20 GB hard drive IBM Travel Mate there is one partition with a clean install of Slackware 11 and soon the other part will be taken for Slackware 10.2.
This way the packages will be build on clean Slackware installs and they should be good for your system. Site primary machine is busy with other things and is now running something that is Slackware current with lots of miscellaneous things, so creating good packages can't be ensured.
