• MacIM can be controlled by escape sequences compatible to TeraTerm
• NFD patch is applied
• Add --enable-nosuid configure option to install without suid by dropping some features

• im-select
• autoconf

git clone https://github.com/rokuyama/screen.git
cd screen/src
./autogen.sh
./configure --prefix=/usr/local --enable-nosuid --enable-macim
make
sudo make install

You need to set imasciikey and imlocalkey appropriately, which can be obtained by im-select command. Your ~/.screenrc should be, e.g.:

imasciikey com.justsystems.inputmethod.atok30.Roman
imlocalkey com.justsystems.inputmethod.atok30.Japanese
macim on

Then, you can control MacIM via escape sequences from terminal-based applications.
