Quite possible. tdebindings is the worst package out of the whole TDE set, the build system is antiquated and broken, and there is a lot of programming by original KDE gurus in languages that I am frankly not familiar with. ;-)
Yeah, I know, tdebindings is a monster, but I built the package in 3.5.13. :(
That said, I wonder what would happen if you set your CXXFLAGS/CFLAGS to include -I/usr/include/tqt
I am doing a rebuild test myself now, so we'll see what happens...
Most likely tdebindings is broken for qt3, but it works fine with tqt3. I personally have no desire to make it work with qt3--as it is not possible to use qt3 and qt4 together in the same program, running TDE on qt3 (instead of tqt3) is a dead end.
