Correct me if I'm wrong, but isn't this exactly the pythonic way of handling
dynamic loading of modules?

try:
    import kdecore
except ImportError:
    # do something else

Of course, this will probably not do what you want in this case, as kdecore
will probably load if it is installed, without regard to whether the current
user is running KDE.  I don't have much experience with this particular
topic yet.
