I've just installed a binary copy of Matrix 1.0-10 in R 2.15.2 patched, 
and I get an error too on attaching it:  "The procedure entry point 
Rf_copyListMatrix could not be located in the dynamic link library 
R.dll."  I'm pretty sure that procedure is available in R.dll currently, 
so I don't know what the real problem is.

I have just rebuilt R, and the same package works fine.  So I'd suggest 
that you download the latest R-patched from CRAN, and hopefully things 
will be fine.
