It is usually better to send big code examples as an attachment, as mail
software can do funny things to it. In this case, it seem that at least one
line has been truncated.

After repairing the code as best I could (and adding stubs for the missing
functions), it compiled without problems in R12B-5.

Which version of Erlang/OTP do you use?
