There are two possibilities:  update the package to follow current R 
usage (which is something the maintainer should do, but if the 
maintainer is not active you may have to do it yourself), or run in an 
old version of R (pre-2.2.0) from before delay() was made defunct.

You may also use this as a sign that the package is not being actively 
maintained, since this change happened in R 2.2.0 in 2005.  I don't know 
if that's reasonable for a collection of annotation data or not.
