Traditionally cron runs under a reduced environment that typically does
not match an interactive environment. Many environment variables are
missing which may affect how the cron job runs. Perhaps if you create a
small command file to print out all your environment variables under
cron and compare that with your interactive environment you may find the
clue which helps. Typically, the PATH variable does not include what you
need to make things work. Since RSH is mentioned, you may need to define
the CVS_RSH variable to make this work under cron.

Rather than run the "cvs" command directly in cron, put it into a
command script where you can control the environment as desired and then
run the script from cron. This helps avoid some of the syntax hazards of
very complex cron commands.
