Ok, I follow. I'm slow. :-)

I have pinentry installed. Of course, built against Qt4 rather than (T)Qt3.

Perhaps that package needs to be rebuilt, explicitly declaring enable-pinentry-qt if the package was built against Qt4. When that option is used, you need to use the standard "qt-dir" options to ensure the configuration knows where to find TQt3:

--with-qt-dir=${QTDIR} \
--with-qt-includes=${QT_INCLUDE_DIR} \
--with-qt-libraries=${QT_LIB_DIR} \

Will the build still fail because moc was renamed to tqmoc? After a quick look at the pinentry sources, yes: the configure script explicitly looks for moc. I'm thinking a patch to change moc->tqmoc, much like we just patched all of the Trinity sources with the new names.

Would a sym link moc->tqmoc succeed? Probably, but only when the TQt3 bin files are installed to a location different from the Qt4 bin files and the "qt-dir" configure options are used to explicitly find TQt3. Using a sym link would be a packaging issue.

We probably should have some notes about unique non Trinity packages that need such attention. Do you know of other packages outside of KDE3/Trinity that build against the old Qt3 and are expected to work within Trinity? For example, the old version of QCAD built against Qt3, but was not a KDE3 app. Thus, that kind of package would not apply to us (although I'm curious whether that version of QCAD would build against TQt3). Any external app needing to interface with Trinity apps through TQt3, such as dialogs, probably needs attention in the wiki.

That's my 2 cents.

With that said, how does pinentry interface with Trinity? Dialogs?
