There is basically no such clause. BUT there is a clause that says that
you may not place additional restrictions on GPL code.

So if you would now take the ODBC manager that is GPLed, and 
embed it in Zope, than you would place some additional restrictions on it,
for example ``the button clause'' in the Zope license, etc.

You can. The author can always do what he wants to do, as he is basically
not bound by his own license ;)

The problem is, that looking externally on this, you cannot
fulfill the license. That's the old KDE/Qt/GPL problem. You probably
noticed that because of this there is no Kimp (KDE port of Gimp). I've
seen it running on Linux Kongress in Cologne this year, but because the
KDE people cannot fulfill the GPL of Gimp, it may not be distributed ;)
