You may install it from precise repository. I tried this in 14.04, it installs fine but I didn't try building any source using it.

1. Add precise repository

   echo "deb  precise main universe multiverse" | sudo tee /etc/apt/sources.list.d/precise.list
   sudo apt-get update
   

2. Install qt3-dev-tools

   sudo apt-get install qt3-dev-tools
   

3. Remove the repository.

   sudo rm /etc/apt/sources.list.d/precise.list
   sudo apt-get update
   

qt3-dev-tools not available in Ubuntu 13.10 . Lucid & precise have it.If you want you can install qt4-dev-tools.

but if you want to install in manual way then

download and install from source.
