`make install` fails on macOS

[vnev]

Running make install results in a permission denied. sudo make install works but fails at sed -i "/usr/bin/ds" -e "s#LIBDIR=.*#LIBDIR=\"/usr/lib/ds\"#" with the error: sed: -i may not be used with stdin

macOS is based on BSD, as far as I know, so there may be some small differences between it and GNU/Linux. These scripts were never meant to be used on macOS.

If you wish you can try to fix it and make it work on macOS as well.
