[BioC] GSVA with entrez ids?

I have an expression set where the featureNames are already human
entrez ids.  What annotation package should I use to run GSVA?  I
tried org.Hs.eg.db, but I get this error:

> coad_es<-gsva(entrezSet, c2BroadSets, min.sz=10, max.sz=500, verbose=TRUE)$es.obs
Mapping identifiers between gene sets and feature names
Error in GeneSetCollection(lapply(what, mapIdentifiers, to, ...,
verbose = verbose)) :
  error in evaluating the argument 'object' in selecting a method for
function 'GeneSetCollection': Error in get(mapName, envir = pkgEnv,
inherits = FALSE) :
  object 'org.Hs.egENTREZID' not found

Am I doing something wrong?
