There are binary copies of DSSS available here for several operating systems and compilers. They are not installers, but simply archives of the complete installation of DSSS. To install on POSIX, simply extract the binary to any prefix you choose, then add /bin to your $PATH environment variable, e.g.: $ export PATH="/opt/dsss/bin:$PATH" The binary is not intended to be installed to /usr (which ideally contains only distribution packages). If you insist on installing to /usr, you will need to move /usr/etc/dsss to /etc/dsss and /usr/etc/rebuilt to /etc/rebuild. To install on Windows, extract the binary to any prefix you choose, then add \bin to your %PATH% environment variable, e.g.: > set PATH=C:\DSSS\bin;%PATH% DSSS will not work installed to a path with spaces, e.g. "C:\Program Files\DSSS"
