I installed leafpad into VL 5.8 SOHO:
slapt-get --install leafpad
Install went fine but it wouldn't run. Executing from the commandline showed that it needs libgnomeprintui. Installing the missing package and it's dependencies (lingnomeprint, libgnomecups) solved the problem. I think whoever maintains the leafpad VL package needs to fix the slack-required file.
