Dear Paul,

something like this really should have been posted to the R-package-devel
list, not to R-devel; as it is here now, I'm crossposting to there for one msg
Please remove R-devel at .. from CC  if/when replying and keep it there.

all of these these are names of  Matrix-package objects..
and I know that yesterday Matrix package version changes (1.1-11
--> 1.1-12) happened on CRAN and hence in servers which update..

So it *could* be this is all just a temporary problem aka "race
situation" , where the check of your package very unhappily
happened exactly at a moment where the new Matrix package was
already there, but not quite ....
seems quite improbable, but then your problem seems "rare"..
