Corrected by setting path so that /usr/local/libexec/cssc preceedes /usr/bin in PATH.And what is this illegal delta for? Note that the program "delta" is part of the POSIX standard and for this reason, people should know that they cannot use the name or other purposes. To be more detailed: the sccs delta program exists since 1972... BTW: the original SCCS implementation I mentioned in the previous mail installs "delta" in $INS_BASE/ccs/bin/delta and let's sccs(1) call "delta" via the absolute path; so there is no interference with other delta programs even if your PATH is not specific or doesn't include the correct delta programm.
