loading lme4 fails - "function 'cholmod_l_start' not providedby package 'Matrix'"

Thanks Prof,

As you can see from my session information (below), I appear to be 
using the same version of Matrix as yourself.  However, I also 
notice that you're using a patched version of 2.8.1 whereas I'm not. 
Could this be the difference?

Did you update your version of Matrix?  It should be 0.99375-20 (or
perhaps -18).  E.g. for me

worked.

R 2.9.0 will check versions when loading a package, but 2.8.1 does
not.

Hello UseRs,

I've just tried to load the lme4 package and got the error message,
"function 'cholmod_l_start' not provided by package 'Matrix'".  I
downloaded the latest version of lme4 and its required packages
(lattice and Matrix) as suggested in the archives and still got this
message.  The FAQ and archives suggested to check the R version

and also the package version requirements.

requirements, but I'm already using the latest available version of
R, 2.8.1.  I'm using Windows XP Professional.

Thanks for any help,
Megan Davies
