David, I disagree: In your case the error message clearly says that "'tcltk' could not be loaded", but you say your package depends on 'tcltk'.

In Johannes' case, the problem is different, because the error message is not that clear.
Johannes, can you install and load the package? Is the DESCRIPTION file
correct? If so, you might want to send the package in a private message...
