We have no problem with Slackware packages. I have just waited for Halloween hysteria to end. Also, there shouldn't be any gibberish in package file name, besides name-version-arch-pkgversion schema. Thanks anyway.
EDIT:
boadicea:/home/platyna/hmz$ ls -a
./ ../ install/ .tgz.tar.gz usr/
Packages for Slackware are compiled with --prefix=/usr and --sysconfdir=/etc, it will also install a file named .tgz.tar.gz in root directory, in short I wouldn't recommend anyone installing this package.
