I have to agree with you. Slackware is rock-solid, but still a beast in terms of software management.
Even between the slackpkg tool and the Slackbuilds website, it's still a lot of tweaking and issues. I had an issue recently on my box where I installed a lot of tools that I needed downloaded from the Slackbuilds website. Didn't run into too many issues getting them installed, however, one day I decided to do the equivalent of a
yum clean all, or
apt-get clean using the slackpkg tool. Well all seemed fine until I ran a command from one of the tools that I installed and it came back with a
command not found message. A little investigating and it seems that when I ran the
slackpkg clean-system command, it really
did clean the system. It seems that since those packages weren't installed using slackpkg the app saw them as packages that were no longer installed. So that led to me having to re-install all those tools again...

apt-show-versions
APT-SHOW-VERSIONS(1p) User Contributed Perl Documentation APT-SHOW-VERSIONS(1p)
NAME
apt-show-versions - Lists available package versions with distribution
DESCRIPTION
apt-show-versions parses the dpkg status file and the APT lists for the installed and available package versions and distribution and shows
upgrade options within the specific distribution of the selected package.
This is really useful if you have a mixed stable/testing environment and want to list all packages which are from testing and can be
upgraded in testing.
apt-show-versions uses caching for the status information of installed and available packages. If you run apt-show-versions as root the
cache is updated as needed. If you run as non-root uses the newest available information, but can't update the cache. If you run as root
with the option -i the cache is initialized or updated only.
SYNOPSIS
apt-show-versions [-h] [[-p] package name] [-a] [-b]
OPTIONS
If you don't give any options the status of all installed packages is printed.
-p package, --package=package
Print available and installed versions for specified package. You can also specify a package name without the option -p. If -p and a
package name are missing, all installed packages are displayed.
-r, --regex
interpret package from option -p as a regex.
-R, --regex-all
like --regex, but also show matching packages which are not installed
-u, --upgradeable
Print only upgradeable packages
-a, --allversions
Print all available versions of the selected packages
-b, --brief
Print only package_name/distribution for upgradeable packages
-v, --verbose
Prints out messages about which Package files are parsed.
-i, --initialize
Initialize or update package cache only (as root). Do this every time when the status of the installed or available packages has
changed. Initialization is done automatically on installation of the package and via a cron.daily job.
-stf file, --status-file=file
Use file as the dpkg status file instead of /var/lib/dpkg/status
-ld directory, --list-dir=directory
Use directory as path to apt's list files instead of /var/state/apt/lists/ or /var/lib/apt/lists/
-h, --help
Prints out command-line help.
EXIT CODES
0 No error
1 Wrong usage
2 apt-show-versions has been called with exactly one package and upgradeable option set, but package is uptodate. As no output has been
requested, this case gets signaled using the exit code.
255 Unspecified error
EXAMPLES
If you want to know for all your installed packages whether they are uptodate or upgradeable, use:
apt-show-versions
If you want to have a list of all upgradeable packages:
apt-show-versions -u
To get a list of all available versions of libc6:
apt-show-versions -a -p libc6
To get information about several packages:
apt-show-versions dpkg apt
apt-show-versions -r ^texlive
To upgrade all packages in testing:
apt-get install `apt-show-versions -u -b | fgrep testing`
