[CM] Really quick question! (SET-MIDI-FILE-VERSIONS!)

[Landspeedrecord]

Hi... I am trying to use SET-MIDI-FILE-VERSIONS! but it isn't working.

The error I get is:

EVAL: undefined function SET-MIDI-FILE-VERSIONS!
   [Condition of type SYSTEM::SIMPLE-UNDEFINED-FUNCTION]

The call to the function that fails looks like this:
(set-midi-file-versions! t)

Any ideas?  I am on XP using cm 2.10 on CLISP and XEmacs

Thanks.
