Thanks for the comments, now I know there is no way to check a programs deps. Again, I assumed that whoever built the package would list the deps they built against-otherwise how did they build it?
ldd does not work for gnucash, give it a try. I realise that it is not easy building a distro like VL, but it does advertise itself as bulit on the ever so stable slackware- which nearly put me off installing it.
I have been very impressed to date with VL 6, I have had no real problems at all apart from when I need to install certain kinds of software. I managed to build mnemosyne myself and it works fine, although the build system and package management is no where near as sophisticated as arch linux-but then arch tends to the other extreme.
All I am really saying is that if a package is in the stable repo and shows up in gslapt then it should be stable and work also gslapt should install the deps by default. Maybe those improvements will turn up in VL 7 or 8.
