The RCS, like ci, co, rlog, etc. can find in Xcode 5.0(with command line developer tool) in mountain lion, but disappear in mavericks with xcode 5.0.1(with command line developer tool).
Is apple abandoned the simple version control tool?

Here's what I did:
Used a time machine backup to restore ci, co, rcs, rcsclean, *rcsdiff, rcsmerge, and rlog* to my directory ~/bin/rcs
Unfortunately, the system needs to find them in /usr/bin. I did not want to add new files to that directory. So I reluctantly (via terminal and sudo) typed
ln -s ~/bin/rcs/* /usr/bin
If you don't want to recompile from source, Rudix is probably the simplest way to install RCS.
The latest version installs in /usr/local/bin and run well in Mavericks. You might want to symlink it in /usr/bin afterward.
