this confusingly worded message is saying that these packages are
import'ed by NAMESPACE, but not listed in Imports: or Depends: in
DESCRIPTION, but...

I don't see anything wrong with what you list here. Perhaps the file is
malformed, or contains non-ASCII characters (tools::showNonASCII might
help) or is otherwise not processed properly (base::read.dcf)? In
addition I am not sure of the consequences of using charset ISO8859-1.
