Back to the original topic. I was able to patch tdewebdev and the package built. My patch is here:

http://humanreadable.nfshost.com/trinity/patches/tqt-fixes/

Unfortunately, tdevelop and tdepim suffer from the same failure:

/dev/shm/tdevelop/lib/util/blockingkprocess.cpp:100: error: 'qt_enter_modal' was not declared in this scope
/dev/shm/tdevelop/lib/util/blockingkprocess.cpp:102: error: 'qt_leave_modal' was not declared in this scope

/dev/shm/tdepim/kresources/lib/kcal_resourcegroupwarebase.cpp:221: error: 'qt_enter_modal' was not declared in this scope
/dev/shm/tdepim/kresources/lib/kcal_resourcegroupwarebase.cpp:223: error: 'qt_leave_modal' was not declared in this scope

I am unable to resolve the errors with a similar patch. I particularly wanted tdepim to build so I can test where the libkcal headers get installed, to possibly resolve a related bug report.
