Installation of newt

Install newt by running the following command: 

sed -e '/install -m 644 $(LIBNEWT)/ s/^/#/' \
    -e '/$(LIBNEWT):/,/rv/ s/^/#/'          \
    -e 's/$(LIBNEWT)/$(LIBNEWTSH)/g'        \
    -i Makefile.in                          &&

./configure --prefix=/usr           \
            --with-gpm-support      \
            --with-python=python3.12 &&
make

This package does not come with a test suite.

Now, as the root user: 

make install

Command Explanations

sed -e ... -i Makefile.in: Disables installation of a static library.

--with-gpm-support: This switch enables mouse support for newt applications through GPM.

--with-python=python3.12: By giving explicitly the name of the directory where python modules reside, this switch prevents building the python2 module.
