Jon: As of version 370 (more precisely, since 369.1), PLT Scheme has a
new unit system, and the DrScheme tool interface uses the new units. So
the code is correct as it is. The problem seems to be that you're using
a package written for version 370 on an installation of version 360.

Grant: Your package should define 'required-core-version' (search Help
Desk) in its info.ss file to be something like "370". That will help
people avoid this problem. Unfortunately, I don't know if it's possible
to make it retroactive for the current package on PLaneT.
