John,
I updated to the current R-patched and now SparseM_0.27 seems to be fine. The
reports I had received complained about:

but it looks fine with the original version of SparseM now...so either this was something
machine specific -- or something that only arose in some intermediate version of R-patched.
Thanks for looking at it,
Roger
