make: *** [Makefile.install_ucb:13: install-dat] Error 1

So basically i am trying to install an older program on a newer kubuntu version 20.10, it was a bit tricky because i needed some old libreries that were no longer part of the stable distribution, i managed to build back the dependencies and the make all command in prompt worked good, but when i type make install i get this error and i am really clueless at this point:

$ make install
mkdir -p /home/teo/rw05/bin
mkdir -p /home/teo/rw05/font
mkdir -p /home/teo/rw05/icc
mkdir -p /home/teo/rw05/demo
mkdir -p /home/teo/rw05/doc
/usr/bin/install ./.radwarerc /home/teo/rw05/.radwarerc
/usr/bin/install ./.radware.bashrc /home/teo/rw05/.radware.bashrc
/usr/bin/install ../font/font.dat /home/teo/rw05/font/font.dat
/usr/bin/install: '../font/font.dat' and '/home/teo/rw05/font/font.dat' are the same file
make: *** [Makefile.install_ucb:13: install-dat] Error 1

Maybe i need to modify something in the makefile or install another thing ? Any help is appreciated !
