The first line of script /usr/share/cvs/contrib/sccs2rcs is #! no -f which is obviously wrong. I guess the reason is that ./configure detected "no" csh. (The script is written in csh.) While fixing the problem, we have to take care that cvs does not become dependant on csh. I see several options: 1) fix the #! line, but tell the find-requires to ignore this (chmod -x the script?) 2) drop the script 3) accept the perl rewrite of sccs2rcs which was present in FC 3 and RHEL 4, but refused upstream (for details, see bug #57974 and http://lists.gnu.org/archive/html/info-cvs/2002-03/msg00273.html) This problem is present not only in current devel, but also in RHEL-5 and in Fedora Core 4--Fedora 7.
Fixed, using option 1).
