Questions about packages you are submitting should go to bioc-devel.
But the answer is, you need to be using R-devel when you develop your package, because the next release of Bioconductor will only work with that version (which will be called R-3.3 upon its release).
The clusterProfiler package has changed between release and devel. In release, its arguments are:
> args(enrichGO)
function (gene, organism = "human", ont = "MF", pvalueCutoff = 0.05,
pAdjustMethod = "BH", universe, qvalueCutoff = 0.2, minGSSize = 5,
readable = FALSE)
In devel they are:
> args(enrichGO)
function (gene, OrgDb, keytype = "ENTREZID", ont = "MF", pvalueCutoff = 0.05,
pAdjustMethod = "BH", universe, qvalueCutoff = 0.2, minGSSize = 5,
readable = FALSE)
?enrichGO
provides further information. Note that in release the organism argument is meant to be a character vector and in devel it appears this argument (no longer named, but required) is supposed to be an OrgDb object. clusterProfiler's NEWS file may also be helpful.
Simply specify the OrgDb that will solve your issue.
E.g.
OrgDb='org.Hs.eg.db'
