[Bioc-devel] biocinstall.R bug(?) : "lite" not installing affyio

After release of Bioconductor 1.9,
I had "faithfully" installed it site-wide, using the usual

   biocLite(lib= <...>)  # default packages

added by a few specific
   biocLite(<mypkg>, ...)

However, today one of our users told me should couldn't use 
the 'affy' package --- which I can confirm ---
because 'affy' on loading tries to load/attach  "affyio",
(and its DESCRIPTION has a 'Depends: ..... affyio' entry)
but 'affyio' has not been installed by the above procedure.
I believe the buglet lies in
   http://bioconductor.org/installScripts/2.4/biocinstall.R

but am really a bit puzzled...
