    Vendor X has no idea what shared libraries exist in/on your system.
    To make certain that Vendor X's executable works, he provides some.

    Linux-ers got used to untarring a source-tree and building it.
    In this case, the libraries used will be the ones that exist on
    the system that built it. Now we have commercial software being
    ported to linux (just like Sun). To make sure it works, these
    vendors will provide libraries.

    Now, if you have 2 or more users running Star Office, you are
    certainly sharing shared libraries so your complaint is not well
    though out. Further, memory mapping a shared file, but not reading it
    yet, is less costly to performance than loading a large-size
    statically-linked file.

    I agree that Linux's new-found fame will cause integration problems
    when commercial software vendors provide their wares.

    It is unfortunate that the first trial ballons will take a lot of heat.
    Eventually vendors' installation programs will check to see what libraries
    your system has and use yours if they are compatible. They will eventually
    understand the power of a symbolic link. In the subject case, Star Office
    should have linked against LibStar-C (or other unique names), etc., and
    during installation, set appropriate symbolic links to compatible
    libraries their installation program found. If a compatible library was
    not found, they would provide theirs with appropriate symbolic links.
