qgvdial is the actual app. It has dependencies on libmosquitto, so you'll need to install that. qgvtp is the phone integration for the n900. You can work without it if you don't want the " Call with qgvdial" option in your n900. qgvnotify is typically not to be run on a regular n900. What error message does it show you?
