Upgraded slackware64-current today (now version 14.1). Afterwards, claws-mail 3.9.2 (compiled on my machine) would not run, puking because it could find no file named libarchive.so.2. As a dirty little workaround, I soft-linked that to /usr/lib64/libarchive.so.13.1.2 and we're running OK for the time being. Other suggestions welcome. T.
