FlyWay is a navigational route planner for pilots. It allows the user to find and select waypoints (airports, navigational aids, and fixes), then calculates distances, courses, wind corrections, and times. Information about the waypoints is provided (including frequencies, elevation, fuel availability, and runway descriptions). The route data is also used to fill in an editable FAA Flight Plan form. FlyWay has an X11 GUI based on the PyQt library.
ConvertAll is a unit conversion program in which units can be combined with multiplication and division operators and can be squared, cubed, etc. The interface is graphical, allowing the units to be selected from lists and the conversions to be made in both directions. Non-linear units (such as temperatures and gauge sizes) are supported. The unit data file can be easily modified to add additional units. ConvertAll is based on the PyQt library.
TreeLine is used to organize and store text data in a tree structure. It is well suited to keeping track of many different types of information. Each node of the tree can contain several defined fields, forming a mini-database. The format of each node can be defined, and the output can be shown on the screen, printed, or exported to HTML. The tree structure is navigated and edited in the left pane of the window, while various views of the child data are shown and editable in the right pane. The data is stored in XML text files. TreeLine is based on the PyQt library.
rpcCalc is a simple RPN (Reverse Polish Notation) calculator for the console. Based on Python's curses module, it starts quickly, has few dependencies, and runs in any Linux console or terminal. It's easy to use, showing buttons for every available command. The commands can be typed, or a mouse can be used (if supported by the terminal).

I'm not sure what the problem is - this problem has
not been reported before. Please reply with the
versions of Python, Qt, PyQt and sip that are installed
on your system.

It appears that the install script is being run with a very old version of Python (1.5.x?). TreeLine requires Python >= 2.1.
Either a proper version of Python is not installed or it is not the default (common on versions of RedHat before 8.0). If a newer version of Python is not installed, it can usually be installed alongside the old version to avoid breaking too many dependancies. If two versions are installed, you may need to run the install script with the full path to the newer version, such as:
Let me know if this doesn't work.
