Add KDELibs caveat so people don't expect it to fully work yet.

    WARNING: this doesn't actually work for running KDE applications yet!

    Please don't just add the Macports patches and expect them to be pulled.
    I'm avoiding adding patches that haven't been committed to KDE upstream
    (which I have commit access to). Instead of requesting I add these,
    consider writing and testing an upstream-suitable patch.

    Thanks for your patience!
