undefined erlang snot?

I tried running a program compiled for OTP R7B in OTP R9B,
and got the following crash:

** exited: {undef,[{erlang,snot,[true]},
                   {shell,eval_loop,2}]} **
** Terminating erlang () **

The line of code causing this must be:

  Thorough = not(lists:member(lazy, Opts)),

I don't quite recall if running OTP R7B applications in OTP
R9B is _guaranteed_ to work, but it does seem to work most
of the time. Is the above problem an OTP bug then?
