Slackware is my favorite Linux distribution. One major “drawback” is its focus on a very specific and limited set of packages (which I also see as a main strength).
There is an intermediary between the traditional DIY way compiling from source and using precompiled packages: a SlackBuild script. The maintainers of Slackware use SlackBuild scripts to automate the compiling process of the official packages.
You can do something similar. If you want to install software not covered in the official repository, do not want to install from untrusted 3rd party repositories/sources while keeping the management benefits of packaged software you can choose to use the scripts provides by the Slackbuilds.org site.
