There was a bug in 2.15.0:  if your package used a package that used a 
recommended package (where "used" means listed as Depends, Suggests, 
Imports...), then you could get this error.

R-patched has this fixed, so you could update to that.  If you don't 
want to update, the workaround is to list "class" explicitly as a 
dependency of your package.
