  I see the logic. My pinentry rebuild was trivial due to building on 3.5.12
with Qt3. Bottom line is all Qt3 reliant apps outside the TDE tree will need
renaming to build against TQt3. Darrell - no, I have no list. It was really just
a quirk that the question popped into my head. After it popped -- my thought was
(a) how would a system install without dragging in Qt4 dependencies if the
package being installed had a Qt dependency but found no q_whatever file? and
(b) how big is the list of files affected?

  I think from a practical standpoint we will just have to see which apps
provide the dependency and go from there. While there may be no choice when
faced with a favorite apps that only builds on Qt4 (there is a choice to install
it or not), the desktop shouldn't force that choice.

  After the TQt3 renaming, will it be possible to rebuild TQt3 & TDE with Qt4
